| WideCharToMultiByte(CodePage, WideCharConversionType, String, Int32, StringBuilder, Int32, String, Boolean) | Maps a UTF-16 (wide character) string to a new character string. The new character string is not necessarily from a multibyte character set. Caution: Using the WideCharToMultiByte(CodePage, WideCharConversionType, String, Int32, StringBuilder, Int32, String, Boolean) function incorrectly can compromise the security of your application. Calling this function can easily cause a buffer overrun because the size of the input buffer indicated by wideCharStr equals the number of characters in the Unicode string, while the size of the output buffer indicated by multiByteStr equals the number of bytes. To avoid a buffer overrun, your application must specify a buffer size appropriate for the data type the buffer receives. Data converted from UTF-16 to non-Unicode encodings is subject to data loss, because a code page might not be able to represent every character used in the specific Unicode data. |
