- pure nothrow @nogc @safe bool
utf_isValidDchar(dcharc); - The Unicode code space is the range of code points [0x000000,0x10FFFF] except the UTF-16 surrogate pairs in the range [0xD800,0xDFFF]
- pure nothrow @nogc @safe int
utf_codeLengthChar(dcharc); - Returns the code length of c in code units.
- pure nothrow @nogc @safe int
utf_codeLength(intsz, dcharc); - Returns the code length of c in code units for the encoding. sz is the encoding: 1 = utf8, 2 = utf16, 4 = utf32.
- pure nothrow @nogc @safe bool
isBidiControl(dcharc); - Checks whether an Unicode code point is a bidirectional control character.
- pure nothrow @nogc @safe string
utf_decodeChar(const(char)[]s, ref size_tridx, out dcharrresult); - Decode a UTF-8 sequence as a single UTF-32 code point.Parameters:
const(char)[] sUTF-8 sequence size_t ridxstarting index in s[], updated to reflect number of code units decoded dchar rresultset to character decoded Returns:null on success, otherwise error message string - pure nothrow @nogc @safe string
utf_decodeWchar(const(wchar)[]s, ref size_tridx, out dcharrresult); - Decode a UTF-16 sequence as a single UTF-32 code point.Parameters:
const(wchar)[] sUTF-16 sequence size_t ridxstarting index in s[], updated to reflect number of code units decoded dchar rresultset to character decoded Returns:null on success, otherwise error message string
