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_decodeChar string utf_decodeChar(const(char)[] s, ref size_t ridx, out dchar rresult): Decode a UTF-8 sequence as a single UTF-32 code point.
utf_decodeWchar string utf_decodeWchar(const(wchar)[] s, ref size_t ridx, out dchar rresult): Decode a UTF-16 sequence as a single UTF-32 code point.
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]
