func AppendRunes ¶

func AppendRunes(dst []uint16, src ...rune) []uint16

AppendRunes appends the UTF-16 encoding of the Unicode code point sequence src to dst.

func DecodeRune ¶

func DecodeRune(r1, r2 rune) rune

DecodeRune returns the UTF-16 decoding of a surrogate pair. If the pair is not a valid UTF-16 surrogate pair, DecodeRune returns the Unicode replacement code point U+FFFD.

func EncodeRune ¶

func EncodeRune(r rune) (r1, r2 rune)

EncodeRune returns the UTF-16 surrogate pair r1, r2 for the given rune.

If the rune is not a valid Unicode code point or does not need encoding, EncodeRune returns U+FFFD, U+FFFD.

func EncodeRunes ¶

func EncodeRunes(dst []uint16, s ...rune) ([]uint16, int)

func EncodedSize ¶

func EncodedSize(s string) int

EncodedSize returns the number of uint16s required to hold the UTF-16 encoding of unicode code points in s.

func IsSurrogate ¶

func IsSurrogate(r rune) bool

IsSurrogate reports whether the specified Unicode code point can appear in a surrogate pair.

func RunesAppend ¶

func RunesAppend(dst []rune, utf16 ...uint16) []rune

RunesAppend decodes all UTF-16 code points in src into the dst, returns the decoded runes.

func RunesDecode ¶

func RunesDecode(d []rune, src ...uint16) (dst []rune, n int)

RunesDecode decodes UTF-16 code points in src into the dst, returns updated dst and count of consumed uint16s from src.

func UTF8Append ¶

func UTF8Append(dst []byte, src ...uint16) []byte

func UTF8Decode ¶

func UTF8Decode(dst []byte, utf16 ...uint16) ([]byte, int)

UTF8Decode transcodes UTF-16 encoding of unicode code points to UTF-8 bytes, returns updated dst and count of consumed uint16s from src.

func UTF8DecodedSize ¶

func UTF8DecodedSize(utf16 ...uint16) (n int, canDecodeInPlace bool)

UTF8DecodedSize returns UTF-8 bytes required to store the decoded UTF-16 encoding of unicode code points.
