GetTextCharsetInfo

The GetTextCharsetInfo function obtains information about the character set of the font that is currently selected into a specified device context.

int GetTextCharsetInfo(
  HDC hdc,                // handle to DC
  LPFONTSIGNATURE lpSig,  // data buffer
  DWORD dwFlags           // reserved; must be zero
);

Parameters

hdc

[in] Handle to a device context. The function obtains information about the font that is selected into this device context.

lpSig

[out] Pointer to a FONTSIGNATURE data structure that receives font-signature information.

If a TrueType font is currently selected into the device context, the FONTSIGNATURE structure receives information that identifies the code page and Unicode subranges for which the font provides glyphs.

If a font other than TrueType is currently selected into the device context, the FONTSIGNATURE structure receives zeroes. In this case, use the TranslateCharsetInfo function to obtain generic font-signature information for the character set.

The lpSig parameter can be NULL if you do not need the FONTSIGNATURE information. In this case, you can also call the GetTextCharset function, which is equivalent to calling GetTextCharsetInfo with lpSig set to NULL.

dwFlags

This parameter is reserved for future use. It must be set to zero.

Return Values

If the function succeeds, the return value identifies the character set of the font currently selected into the specified device context. The following character-set identifiers are defined:

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

Korean Windows:

JOHAB_CHARSET

Middle-Eastern Windows:

HEBREW_CHARSET
ARABIC_CHARSET

Thai Windows:

THAI_CHARSET

If the function fails, the return value is DEFAULT_CHARSET.
