Functions

isUniAlpha
bool isUniAlpha(dchar c)

Return !=0 if unicode alpha. Use table from C99 Appendix D.

utf_codeLength
int utf_codeLength(int sz, dchar c)

Returns the code length of c in code units for the encoding. sz is the encoding: 1 = utf8, 2 = utf16, 4 = utf32.

utf_codeLengthChar
int utf_codeLengthChar(dchar c)

Returns the code length of c in code units.

utf_codeLengthWchar
int utf_codeLengthWchar(dchar c)
Undocumented in source. Be warned that the author may not have intended to support it.
utf_decodeChar
string utf_decodeChar(const(char)[] s, size_t ridx, dchar rresult)

Decode a UTF-8 sequence as a single UTF-32 code point.

utf_decodeWchar
string utf_decodeWchar(const(wchar)[] s, size_t ridx, dchar rresult)

Decode a UTF-16 sequence as a single UTF-32 code point.

utf_encode
void utf_encode(int sz, void* s, dchar c)
Undocumented in source. Be warned that the author may not have intended to support it.
utf_encodeChar
void utf_encodeChar(char* s, dchar c)
Undocumented in source. Be warned that the author may not have intended to support it.
utf_encodeWchar
void utf_encodeWchar(wchar* s, dchar c)
Undocumented in source. Be warned that the author may not have intended to support it.
utf_isValidDchar
bool utf_isValidDchar(dchar c)

The Unicode code space is the range of code points [0x000000,0x10FFFF] except the UTF-16 surrogate pairs in the range [0xD800,0xDFFF]
