现在我可以得到unicode值，我必须从unicode值调用之前得到它的字符集
HFONT CreateFont( int nHeight, // height of font int nWidth, // average character width int nEscapement, // angle of escapement int nOrientation, // base-line orientation angle int fnWeight, // font weight DWORD fdwItalic, // italic attribute option DWORD fdwUnderline, // underline attribute option DWORD fdwStrikeOut, // strikeout attribute option DWORD fdwCharSet, // character set identifier DWORD fdwOutputPrecision, // output precision DWORD fdwClipPrecision, // clipping precision DWORD fdwQuality, // output quality DWORD fdwPitchAndFamily, // pitch and family LPCTSTR lpszFace // typeface name ); 我从MSDN得到了以下信息：
fdwCharSet
[in] Specifies the character set. The following values are predefined: ANSI_CHARSET BALTIC_CHARSET CHINESEBIG5_CHARSET DEFAULT_CHARSET EASTEUROPE_CHARSET GB2312_CHARSET GREEK_CHARSET HANGUL_CHARSET MAC_CHARSET OEM_CHARSET RUSSIAN_CHARSET SHIFTJIS_CHARSET SYMBOL_CHARSET TURKISH_CHARSET VIETNAMESE_CHARSET Korean language edition of Windows: JOHAB_CHARSET Middle East language edition of Windows: ARABIC_CHARSET HEBREW_CHARSET Thai language edition of Windows: THAI_CHARSET The OEM_CHARSET value specifies a character set that is operating-system dependent. Windows 95/98/Me: You can use the DEFAULT_CHARSET value to allow the name and size of a font to fully describe the logical font. If the specified font name does not exist, a font from any character set can be substituted for the specified font, so you should use DEFAULT_CHARSET sparingly to avoid unexpected results.
这是我现在拥有的：
FX_INT32 CharSetFromUnicode(FX_WORD word) { int nACP = GetACP(); switch (nACP) { case 932: case 936: case 950: case 949: if ((word >= 0x2E80 && word <= 0x2EFF) || (word >= 0x3000 && word <= 0x303F) || (word >= 0x3200 && word <= 0x32FF) || (word >= 0x3300 && word <= 0x33FF) || (word >= 0x3400 && word <= 0x4DB5) || (word >= 0x4E00 && word <= 0x9FFF) || (word >= 0xF900 && word <= 0xFAFF) || (word >= 0xFE30 && word <= 0xFE4F) || (word >= 0x20000 && word <= 0x2A6D6) || (word >= 0x2F800 && word <= 0x2FA1F)) { switch (nACP) { case 932: return SHIFTJIS_CHARSET; case 936: case 950: return GB2312_CHARSET; case 949: return HANGUL_CHARSET; } } break; } //find new charset if ((word >= 0x4E00 && word <= 0x9FA5) || (word >= 0xE7C7 && word <= 0xE7F3) || (word >= 0x3000 && word <= 0x303F) || //）"《" "》" "。" "、" (word >= 0x2000 && word <= 0x206F)) { return GB2312_CHARSET; } if (((word >= 0x3040) && (word <= 0x309F)) || ((word >= 0x30A0) && (word <= 0x30FF)) || ((word >= 0x31F0) && (word <= 0x31FF)) || ((word >= 0xFF00) && (word <= 0xFFEF)) ) { return SHIFTJIS_CHARSET; } if (((word >= 0xAC00) && (word <= 0xD7AF)) || ((word >= 0x1100) && (word <= 0x11FF)) || ((word >= 0x3130) && (word <= 0x318F))) { return HANGUL_CHARSET; } if (word >= 0x0E00 && word <= 0x0E7F) return THAI_CHARSET; if ((word >= 0x0370 && word <= 0x03FF) || (word >= 0x1F00 && word <= 0x1FFF)) return GREEK_CHARSET; if ((word >= 0x0600 && word <= 0x06FF) || (word >= 0xFB50 && word <= 0xFEFC)) return ARABIC_CHARSET; if (word >= 0x0590 && word <= 0x05FF) return HEBREW_CHARSET; if (word >= 0x0400 && word <= 0x04FF) return RUSSIAN_CHARSET; if (word == 0x11E || word == 0x11F || word == 0x130 || word == 0x131 || word == 0x15E || word == 0x15F) return TURKISH_CHARSET; if (word >= 0x0100 && word <= 0x024F) return EASTEUROPE_CHARSET; if (word >= 0x1E00 && word <= 0x1EFF) return VIETNAMESE_CHARSET; return GB2312_CHARSET; }
但function不能正常工作。 任何人都可以帮助我解决它？
一般来说，没有保证的方法来猜测编码。
然而，在实践中可以猜测。 例如，由Mozilla创建的非常好的通用字符集检测库： uchardet 。
它在Firefox中被用来自动猜测你所访问的随机页面的字符集（如果有的话，它们并不总是提供适当的编码），而且在实践中似乎很好。
