```go
type MarshalerContext interface {
MarshalJSON(context.Context) ([]byte, error)
}
type UnmarshalerContext interface {
UnmarshalJSON(context.Context, []byte) error
}
```
### Add DecodeFieldPriorityFirstWin option ( #242 )
In the default behavior, go-json, like encoding/json, will reflect the result of the last evaluation when a field with the same name exists. I've added new options to allow you to change this behavior. `json.DecodeFieldPriorityFirstWin` option reflects the result of the first evaluation if a field with the same name exists. This behavior has a performance advantage as it allows the subsequent strings to be skipped if all fields have been evaluated.

- invalid UTF-8 is coerced to valid UTF-8 ( without performance down )
### Fix encoder
- Fixed handling of MarshalJSON of function type
### Fix decoding of slice of pointer type
If there is a pointer value, go-json will use it. (This behavior is necessary to achieve the ability to prioritize pre-filled values). However, since slices are reused internally, there was a bug that referred to the previous pointer value. Therefore, it is not necessary to refer to the pointer value in advance for the slice element, so we explicitly initialize slice element by `nil`.
# v0.4.8 - 2021/3/21
### Reduce memory usage at compile time
* go-json have used about 2GB of memory at compile time, but now it can compile with about less than 550MB.
### Fix any encoder's bug
* Add many test cases for encoder
* Fix composite type ( slice/array/map )
* Fix pointer types
* Fix encoding of MarshalJSON or MarshalText or json.Number type
### Refactor encoder
* Change package layout for reducing memory usage at compile
* Remove anonymous and only operation
* Remove root property from encodeCompileContext and opcode
### Fix CI
* Add Go 1.16
* Remove Go 1.13
* Fix `make cover` task
### Number/Delim/Token/RawMessage use the types defined in encoding/json by type alias
# v0.4.7 - 2021/02/22
### Fix decoder
* Fix decoding of deep recursive structure
* Fix decoding of embedded unexported pointer field
* Fix invalid test case
* Fix decoding of invalid value
* Fix decoding of prefilled value
* Fix not being able to return UnmarshalTypeError when it should be returned
* Fix decoding of null value
* Fix decoding of type of null string
* Use pre allocated pointer if exists it at decoding
### Reduce memory usage at compile
* Integrate int/int8/int16/int32/int64 and uint/uint8/uint16/uint32/uint64 operation to reduce memory usage at compile
### Remove unnecessary optype

Fast JSON encoder/decoder compatible with encoding/json for Go
<img width="400px" src="https://user-images.githubusercontent.com/209884/92572337-42b42900-f2bf-11ea-973a-c74a359553a5.png"></img>
# Roadmap
```
* version ( expected release date )
* v0.7.0
|
| while maintaining compatibility with encoding/json, we will add convenient APIs
|
v
* v1.0.0
```
We are accepting requests for features that will be implemented between v0.7.0 and v.1.0.0.
If you have the API you need, please submit your issue [here](https://github.com/goccy/go-json/issues).
For example, I'm thinking of supporting `context.Context` of `json.Marshaler` and decoding using JSON Path.
# Features
- Drop-in replacement of `encoding/json`
- Fast ( See [Benchmark section](https://github.com/goccy/go-json#benchmarks) )
- Flexible customization with options
- Coloring the encoded string
- Can propagate context.Context to `MarshalJSON` or `UnmarshalJSON`
# Installation
```
go get github.com/goccy/go-json
```
# How to use

- `json-iterator/go` isn't compatible with `encoding/json` in many ways (e.g. https://github.com/json-iterator/go/issues/229 ), but it hasn't been supported for a long time.
- `segmentio/encoding/json` is well supported for encoders, but some are not supported for decoder APIs such as `Token` ( streaming decode )
## Other libraries
- [jingo](https://github.com/bet365/jingo)
I tried the benchmark but it didn't work.
Also, it seems to panic when it receives an unexpected value because there is no error handling...
- [ffjson](https://github.com/pquerna/ffjson)
Benchmarking gave very slow results.
It seems that it is assumed that the user will use the buffer pool properly.
Also, development seems to have already stopped

# How it works
`go-json` is very fast in both encoding and decoding compared to other libraries.
It's easier to implement by using automatic code generation for performance or by using a dedicated interface, but `go-json` dares to stick to compatibility with `encoding/json` and is the simple interface. Despite this, we are developing with the aim of being the fastest library.
Here, we explain the various speed-up techniques implemented by `go-json`.
## Basic technique
The techniques listed here are the ones used by most of the libraries listed above.
### Buffer reuse
Since the only value required for the result of `json.Marshal(interface{}) ([]byte, error)` is `[]byte`, the only value that must be allocated during encoding is the return value `[]byte` .
Also, as the number of allocations increases, the performance will be affected, so the number of allocations should be kept as low as possible when creating `[]byte`.
Therefore, there is a technique to reduce the number of times a new buffer must be allocated by reusing the buffer used for the previous encoding by using `sync.Pool`.
Finally, you allocate a buffer that is as long as the resulting buffer and copy the contents into it, you only need to allocate the buffer once in theory.
```go
type buffer struct {
data []byte
}
var bufPool = sync.Pool{
New: func() interface{} {
return &buffer{data: make([]byte, 0, 1024)}
},
}
buf := bufPool.Get().(*buffer)
data := encode(buf.data) // reuse buf.data
newBuf := make([]byte, len(data))
copy(newBuf, buf)
buf.data = data
bufPool.Put(buf)
```
### Elimination of reflection
As you know, the reflection operation is very slow.
Therefore, using the fact that the address position where the type information is stored is fixed for each binary ( we call this `typeptr` ),
we can use the address in the type information to call a pre-built optimized process.
For example, you can get the address to the type information from `interface{}` as follows and you can use that information to call a process that does not have reflection.
To process without reflection, pass a pointer (`unsafe.Pointer`) to the value is stored.
```go
type emptyInterface struct {
typ unsafe.Pointer
ptr unsafe.Pointer
}
var typeToEncoder = map[uintptr]func(unsafe.Pointer)([]byte, error){}
func Marshal(v interface{}) ([]byte, error) {
iface := (*emptyInterface)(unsafe.Pointer(&v)
typeptr := uintptr(iface.typ)
if enc, exists := typeToEncoder[typeptr]; exists {
return enc(iface.ptr)
}
...
}
```
※ In reality, `typeToEncoder` can be referenced by multiple goroutines, so exclusive control is required.
## Unique speed-up technique
## Encoder
### Do not escape arguments of `Marshal`
`json.Marshal` and `json.Unmarshal` receive `interface{}` value and they perform type determination dynamically to process.
In normal case, you need to use the `reflect` library to determine the type dynamically, but since `reflect.Type` is defined as `interface`, when you call the method of `reflect.Type`, The reflect's argument is escaped.
Therefore, the arguments for `Marshal` and `Unmarshal` are always escape to the heap.
However, `go-json` can use the feature of `reflect.Type` while avoiding escaping.
`reflect.Type` is defined as `interface`, but in reality `reflect.Type` is implemented only by the structure `rtype` defined in the `reflect` package.
For this reason, to date `reflect.Type` is the same as `*reflect.rtype`.
Therefore, by directly handling `*reflect.rtype`, which is an implementation of `reflect.Type`, it is possible to avoid escaping because it changes from `interface` to using `struct`.
The technique for working with `*reflect.rtype` directly from `go-json` is implemented at [rtype.go](https://github.com/goccy/go-json/blob/master/internal/runtime/rtype.go)
Also, the same technique is cut out as a library ( https://github.com/goccy/go-reflect )
Initially this feature was the default behavior of `go-json`.
But after careful testing, I found that I passed a large value to `json.Marshal()` and if the argument could not be assigned to the stack, it could not be properly escaped to the heap (a bug in the Go compiler).
Therefore, this feature will be provided as an **optional** until this issue is resolved.
To use it, add `NoEscape` like `MarshalNoEscape()`
### Encoding using opcode sequence
I explained that you can use `typeptr` to call a pre-built process from type information.
In other libraries, this dedicated process is processed by making it an function calling like anonymous function, but function calls are inherently slow processes and should be avoided as much as possible.
Therefore, `go-json` adopted the Instruction-based execution processing system, which is also used to implement virtual machines for programming language.
If it is the first type to encode, create the opcode ( instruction ) sequence required for encoding.
From the second time onward, use `typeptr` to get the cached pre-built opcode sequence and encode it based on it. An example of the opcode sequence is shown below.
```go
json.Marshal(struct{
X int `json:"x"`
Y string `json:"y"`
}{X: 1, Y: "hello"})
```
When encoding a structure like the one above, create a sequence of opcodes like this:
```
- opStructFieldHead ( `{` )
- opStructFieldInt ( `"x": 1,` )
- opStructFieldString ( `"y": "hello"` )
- opStructEnd ( `}` )
- opEnd
```
※ When processing each operation, write the letters on the right.
In addition, each opcode is managed by the following structure (
Pseudo code ).
```go
type opType int
const (
opStructFieldHead opType = iota
opStructFieldInt
opStructFieldStirng
opStructEnd
opEnd
)
type opcode struct {
op opType
key []byte
next *opcode
}
```
The process of encoding using the opcode sequence is roughly implemented as follows.
```go
func encode(code *opcode, b []byte, p unsafe.Pointer) ([]byte, error) {
for {
switch code.op {
case opStructFieldHead:
b = append(b, '{')
code = code.next
case opStructFieldInt:
b = append(b, code.key...)
b = appendInt((*int)(unsafe.Pointer(uintptr(p)+code.offset)))
code = code.next
case opStructFieldString:
b = append(b, code.key...)
b = appendString((*string)(unsafe.Pointer(uintptr(p)+code.offset)))
code = code.next
case opStructEnd:
b = append(b, '}')
code = code.next
case opEnd:
goto END
}
}
END:
return b, nil
}
```
In this way, the huge `switch-case` is used to encode by manipulating the linked list opcodes to avoid unnecessary function calls.
### Opcode sequence optimization
One of the advantages of encoding using the opcode sequence is the ease of optimization.
The opcode sequence mentioned above is actually converted into the following optimized operations and used.
```
- opStructFieldHeadInt ( `{"x": 1,` )
- opStructEndString ( `"y": "hello"}` )
- opEnd
```
It has been reduced from 5 opcodes to 3 opcodes !
Reducing the number of opcodees means reducing the number of branches with `switch-case`.
In other words, the closer the number of operations is to 1, the faster the processing can be performed.
In `go-json`, optimization to reduce the number of opcodes itself like the above and it speeds up by preparing opcodes with optimized paths.
### Change recursive call from CALL to JMP
Recursive processing is required during encoding if the type is defined recursively as follows:
```go
type T struct {
X int
U *U
}
type U struct {
T *T
}
b, err := json.Marshal(&T{
X: 1,
U: &U{
T: &T{
X: 2,
},
},
})
fmt.Println(string(b)) // {"X":1,"U":{"T":{"X":2,"U":null}}}
```
In `go-json`, recursive processing is processed by the operation type of ` opStructFieldRecursive`.
In this operation, after acquiring the opcode sequence used for recursive processing, the function is **not** called recursively as it is, but the necessary values ​​are saved by itself and implemented by moving to the next operation.
The technique of implementing recursive processing with the `JMP` operation while avoiding the `CALL` operation is a famous technique for implementing a high-speed virtual machine.
For more details, please refer to [the article](https://engineering.mercari.com/blog/entry/1599563768-081104c850) ( but Japanese only ).
### Dispatch by typeptr from map to slice
When retrieving the data cached from the type information by `typeptr`, we usually use map.
Map requires exclusive control, so use `sync.Map` for a naive implementation.
However, this is slow, so it's a good idea to use the `atomic` package for exclusive control as implemented by `segmentio/encoding/json` ( https://github.com/segmentio/encoding/blob/master/json/codec.go#L41-L55 ).
This implementation slows down the set instead of speeding up the get, but it works well because of the nature of the library, it encodes much more for the same type.
However, as a result of profiling, I noticed that `runtime.mapaccess2` accounts for a significant percentage of the execution time. So I thought if I could change the lookup from map to slice.
There is an API named `typelinks` defined in the `runtime` package that the `reflect` package uses internally.
This allows you to get all the type information defined in the binary at runtime.
The fact that all type information can be acquired means that by constructing slices in advance with the acquired total number of type information, it is possible to look up with the value of `typeptr` without worrying about out-of-range access.
However, if there is too much type information, it will use a lot of memory, so by default we will only use this optimization if the slice size fits within **2Mib** .
If this approach is not available, it will fall back to the `atomic` based process described above.
If you want to know more, please refer to the implementation [here](https://github.com/goccy/go-json/blob/master/internal/runtime/type.go#L36-L100)
## Decoder
### Dispatch by typeptr from map to slice
Like the encoder, the decoder also uses typeptr to call the dedicated process.
### Faster termination character inspection using NUL character
In order to decode, you have to traverse the input buffer character by position.
At that time, if you check whether the buffer has reached the end, it will be very slow.
`buf` : `[]byte` type variable. holds the string passed to the decoder
`cursor` : `int64` type variable. holds the current read position
```go
buflen := len(buf)
for ; cursor < buflen; cursor++ { // compare cursor and buflen at all times, it is so slow.
switch buf[cursor] {
case ' ', '\n', '\r', '\t':
}
}
```
Therefore, by adding the `NUL` (`\000`) character to the end of the read buffer as shown below, it is possible to check the termination character at the same time as other characters.
```go
for {
switch buf[cursor] {
case ' ', '\n', '\r', '\t':
case '\000':
return nil
}
cursor++
}
```
### Use Boundary Check Elimination
Due to the `NUL` character optimization, the Go compiler does a boundary check every time, even though `buf[cursor]` does not cause out-of-range access.
Therefore, `go-json` eliminates boundary check by fetching characters for hotspot by pointer operation. For example, the following code.
```go
func char(ptr unsafe.Pointer, offset int64) byte {
return *(*byte)(unsafe.Pointer(uintptr(ptr) + uintptr(offset)))
}
p := (*sliceHeader)(&unsafe.Pointer(buf)).data
for {
switch char(p, cursor) {
case ' ', '\n', '\r', '\t':
case '\000':
return nil
}
cursor++
}
```
### Checking the existence of fields of struct using Bitmaps
I found by the profiling result, in the struct decode, lookup process for field was taking a long time.
For example, consider decoding a string like `{"a":1,"b":2,"c":3}` into the following structure:
```go
type T struct {
A int `json:"a"`
B int `json:"b"`
C int `json:"c"`
}
```
At this time, it was found that it takes a lot of time to acquire the decoding process corresponding to the field from the field name as shown below during the decoding process.
```go
fieldName := decodeKey(buf, cursor) // "a" or "b" or "c"
decoder, exists := fieldToDecoderMap[fieldName] // so slow
if exists {
decoder(buf, cursor)
} else {
skipValue(buf, cursor)
}
```
To improve this process, `json-iterator/go` is optimized so that it can be branched by switch-case when the number of fields in the structure is 10 or less (switch-case is faster than map). However, there is a risk of hash collision because the value hashed by the FNV algorithm is used for conditional branching. Also, `gojay` processes this part at high speed by letting the library user yourself write `switch-case`.
`go-json` considers and implements a new approach that is different from these. I call this **bitmap field optimization**.
The range of values ​​per character can be represented by `[256]byte`. Also, if the number of fields in the structure is 8 or less, `int8` type can represent the state of each field.
In other words, it has the following structure.
- Base ( 8bit ): `00000000`
- Key "a": `00000001` ( assign key "a" to the first bit )
- Key "b": `00000010` ( assign key "b" to the second bit )
- Key "c": `00000100` ( assign key "c" to the third bit )
Bitmap structure is the following
```
| key index(0) |
------------------------
0 | 00000000 |
1 | 00000000 |
~~ | |
97 (a) | 00000001 |
98 (b) | 00000010 |
99 (c) | 00000100 |
~~ | |
255 | 00000000 |
```
You can think of this as a Bitmap with a height of `256` and a width of the maximum string length in the field name.
In other words, it can be represented by the following type .
```go
[maxFieldKeyLength][256]int8
```
When decoding a field character, check whether the corresponding character exists by referring to the pre-built bitmap like the following.
```go
var curBit int8 = math.MaxInt8 // 11111111
c := char(buf, cursor)
bit := bitmap[keyIdx][c]
curBit &= bit
if curBit == 0 {
// not found field
}
```
If `curBit` is not `0` until the end of the field string, then the string is
You may have hit one of the fields.
But the possibility is that if the decoded string is shorter than the field string, you will get a false hit.
- input: `{"a":1}`
```go
type T struct {
X int `json:"abc"`
}
```
※ Since `a` is shorter than `abc`, it can decode to the end of the field character without `curBit` being 0.
Rest assured. In this case, it doesn't matter because you can tell if you hit by comparing the string length of `a` with the string length of `abc`.
Finally, calculate the position of the bit where `1` is set and get the corresponding value, and you're done.
Using this technique, field lookups are possible with only bitwise operations and access to slices.
`go-json` uses a similar technique for fields with 9 or more and 16 or less fields. At this time, Bitmap is constructed as `[maxKeyLen][256]int16` type.
Currently, this optimization is not performed when the maximum length of the field name is long (specifically, 64 bytes or more) in addition to the limitation of the number of fields from the viewpoint of saving memory usage.
### Others
I have done a lot of other optimizations. I will find time to write about them. If you have any questions about what's written here or other optimizations, please visit the `#go-json` channel on `gophers.slack.com` .

// Marshal returns the JSON encoding of v.
//
// Marshal traverses the value v recursively.
// If an encountered value implements the Marshaler interface
// and is not a nil pointer, Marshal calls its MarshalJSON method
// to produce JSON. If no MarshalJSON method is present but the
// value implements encoding.TextMarshaler instead, Marshal calls
// its MarshalText method and encodes the result as a JSON string.
// The nil pointer exception is not strictly necessary
// but mimics a similar, necessary exception in the behavior of
// UnmarshalJSON.
//
// Otherwise, Marshal uses the following type-dependent default encodings:
//
// Boolean values encode as JSON booleans.
//
// Floating point, integer, and Number values encode as JSON numbers.
//
// String values encode as JSON strings coerced to valid UTF-8,
// replacing invalid bytes with the Unicode replacement rune.
// The angle brackets "<" and ">" are escaped to "\u003c" and "\u003e"
// to keep some browsers from misinterpreting JSON output as HTML.
// Ampersand "&" is also escaped to "\u0026" for the same reason.
// This escaping can be disabled using an Encoder that had SetEscapeHTML(false)
// called on it.
//
// Array and slice values encode as JSON arrays, except that
// []byte encodes as a base64-encoded string, and a nil slice
// encodes as the null JSON value.
//
// Struct values encode as JSON objects.
// Each exported struct field becomes a member of the object, using the
// field name as the object key, unless the field is omitted for one of the
// reasons given below.
//
// The encoding of each struct field can be customized by the format string
// stored under the "json" key in the struct field's tag.
// The format string gives the name of the field, possibly followed by a
// comma-separated list of options. The name may be empty in order to
// specify options without overriding the default field name.
//
// The "omitempty" option specifies that the field should be omitted
// from the encoding if the field has an empty value, defined as
// false, 0, a nil pointer, a nil interface value, and any empty array,
// slice, map, or string.
//
// As a special case, if the field tag is "-", the field is always omitted.
// Note that a field with name "-" can still be generated using the tag "-,".
//
// Examples of struct field tags and their meanings:
//
// // Field appears in JSON as key "myName".
// Field int `json:"myName"`
//
// // Field appears in JSON as key "myName" and
// // the field is omitted from the object if its value is empty,
// // as defined above.
// Field int `json:"myName,omitempty"`
//
// // Field appears in JSON as key "Field" (the default), but
// // the field is skipped if empty.
// // Note the leading comma.
// Field int `json:",omitempty"`
//
// // Field is ignored by this package.
// Field int `json:"-"`
//
// // Field appears in JSON as key "-".
// Field int `json:"-,"`
//
// The "string" option signals that a field is stored as JSON inside a
// JSON-encoded string. It applies only to fields of string, floating point,
// integer, or boolean types. This extra level of encoding is sometimes used
// when communicating with JavaScript programs:
//
// Int64String int64 `json:",string"`
//
// The key name will be used if it's a non-empty string consisting of
// only Unicode letters, digits, and ASCII punctuation except quotation
// marks, backslash, and comma.
//
// Anonymous struct fields are usually marshaled as if their inner exported fields
// were fields in the outer struct, subject to the usual Go visibility rules amended
// as described in the next paragraph.
// An anonymous struct field with a name given in its JSON tag is treated as
// having that name, rather than being anonymous.
// An anonymous struct field of interface type is treated the same as having
// that type as its name, rather than being anonymous.
//
// The Go visibility rules for struct fields are amended for JSON when
// deciding which field to marshal or unmarshal. If there are
// multiple fields at the same level, and that level is the least
// nested (and would therefore be the nesting level selected by the
// usual Go rules), the following extra rules apply:
//
// 1) Of those fields, if any are JSON-tagged, only tagged fields are considered,
// even if there are multiple untagged fields that would otherwise conflict.
//
// 2) If there is exactly one field (tagged or not according to the first rule), that is selected.
//
// 3) Otherwise there are multiple fields, and all are ignored; no error occurs.
//
// Handling of anonymous struct fields is new in Go 1.1.
// Prior to Go 1.1, anonymous struct fields were ignored. To force ignoring of
// an anonymous struct field in both current and earlier versions, give the field
// a JSON tag of "-".
//
// Map values encode as JSON objects. The map's key type must either be a
// string, an integer type, or implement encoding.TextMarshaler. The map keys
// are sorted and used as JSON object keys by applying the following rules,
// subject to the UTF-8 coercion described for string values above:
// - string keys are used directly
// - encoding.TextMarshalers are marshaled
// - integer keys are converted to strings
//
// Pointer values encode as the value pointed to.
// A nil pointer encodes as the null JSON value.
//
// Interface values encode as the value contained in the interface.
// A nil interface value encodes as the null JSON value.
//
// Channel, complex, and function values cannot be encoded in JSON.
// Attempting to encode such a value causes Marshal to return
// an UnsupportedTypeError.
//
// JSON cannot represent cyclic data structures and Marshal does not
// handle them. Passing cyclic structures to Marshal will result in
// an infinite recursion.

// Unmarshal parses the JSON-encoded data and stores the result

// Unmarshal uses the inverse of the encodings that

//
// To unmarshal JSON into a pointer, Unmarshal first handles the case of
// the JSON being the JSON literal null. In that case, Unmarshal sets
// the pointer to nil. Otherwise, Unmarshal unmarshals the JSON into
// the value pointed at by the pointer. If the pointer is nil, Unmarshal
// allocates a new value for it to point to.
//
// To unmarshal JSON into a value implementing the Unmarshaler interface,
// Unmarshal calls that value's UnmarshalJSON method, including
// when the input is a JSON null.
// Otherwise, if the value implements encoding.TextUnmarshaler
// and the input is a JSON quoted string, Unmarshal calls that value's
// UnmarshalText method with the unquoted form of the string.
//
// To unmarshal JSON into a struct, Unmarshal matches incoming object
// keys to the keys used by Marshal (either the struct field name or its tag),
// preferring an exact match but also accepting a case-insensitive match. By
// default, object keys which don't have a corresponding struct field are
// ignored (see Decoder.DisallowUnknownFields for an alternative).
//
// To unmarshal JSON into an interface value,
// Unmarshal stores one of these in the interface value:
//
// bool, for JSON booleans
// float64, for JSON numbers
// string, for JSON strings
// []interface{}, for JSON arrays
// map[string]interface{}, for JSON objects
// nil for JSON null
//
// To unmarshal a JSON array into a slice, Unmarshal resets the slice length
// to zero and then appends each element to the slice.
// As a special case, to unmarshal an empty JSON array into a slice,
// Unmarshal replaces the slice with a new empty slice.
//
// To unmarshal a JSON array into a Go array, Unmarshal decodes
// JSON array elements into corresponding Go array elements.
// If the Go array is smaller than the JSON array,
// the additional JSON array elements are discarded.
// If the JSON array is smaller than the Go array,
// the additional Go array elements are set to zero values.
//
// To unmarshal a JSON object into a map, Unmarshal first establishes a map to
// use. If the map is nil, Unmarshal allocates a new map. Otherwise Unmarshal
// reuses the existing map, keeping existing entries. Unmarshal then stores
// key-value pairs from the JSON object into the map. The map's key type must
// either be any string type, an integer, implement json.Unmarshaler, or
// implement encoding.TextUnmarshaler.
//
// If a JSON value is not appropriate for a given target type,
// or if a JSON number overflows the target type, Unmarshal
// skips that field and completes the unmarshaling as best it can.
// If no more serious errors are encountered, Unmarshal returns
// an UnmarshalTypeError describing the earliest such error. In any
// case, it's not guaranteed that all the remaining fields following
// the problematic one will be unmarshaled into the target object.
//
// The JSON null value unmarshals into an interface, map, pointer, or slice
// by setting that Go value to nil. Because null is often used in JSON to mean
// ``not present,'' unmarshaling a JSON null into any other Go type has no effect
// on the value and produces no error.
//
// When unmarshaling quoted strings, invalid UTF-8 or
// invalid UTF-16 surrogate pairs are not treated as an error.
// Instead, they are replaced by the Unicode replacement
// character U+FFFD.
//
