Functions
GetNlsSectionName
Construct a name of NLS section. Parameters: CodePage Code page number. Base Integer base used for converting to string. Usually set to 10. Unknown As the name suggests the meaning of this parameter is unknown. The native version of Kernel32 passes it as the third parameter to NlsConvertIntegerToString function, which is used for the actual conversion of the code page number. BaseName Base name of the section. (ex. "\\Nls\\NlsSectionCP") Result Buffer that will hold the constructed name. ResultSize Size of the buffer for the result. Returns: TRUE if the buffer was large enough and was filled with the requested information, FALSE otherwise.
BOOL WINAPI	GetNlsSectionName (UINT CodePage, UINT Base, ULONG Unknown, LPSTR BaseName, LPSTR Result, ULONG ResultSize)
GetCPFileNameFromRegistry
Get file name of code page definition file. Parameters: CodePage Code page number to get file name of. FileName Buffer that is filled with file name of successful return. Can be set to NULL. FileNameSize Size of the buffer to hold file name in WCHARs. Returns: TRUE if the file name was retrieved, FALSE otherwise.

WideCharToMultiByte
Convert a wide-charater string to closest multi-byte equivalent. Parameters: CodePage Code page to be used to perform the conversion. It can be also one of the special values (CP_ACP for ANSI code page, CP_MACCP for Macintosh code page, CP_OEMCP for OEM code page, CP_THREAD_ACP for thread active code page, CP_UTF7 or CP_UTF8). Flags Additional conversion flags (WC_NO_BEST_FIT_CHARS, WC_COMPOSITECHECK, WC_DISCARDNS, WC_SEPCHARS, WC_DEFAULTCHAR). WideCharString Points to the wide-character string to be converted. WideCharCount Size in WCHARs of WideCharStr, or 0 if the caller just wants to know how large WideCharString should be for a successful conversion. MultiByteString Points to the buffer to receive the translated string. MultiByteCount Specifies the size in bytes of the buffer pointed to by the MultiByteString parameter. If this value is zero, the function returns the number of bytes required for the buffer. DefaultChar Points to the character used if a wide character cannot be represented in the specified code page. If this parameter is NULL, a system default value is used. UsedDefaultChar Points to a flag that indicates whether a default character was used. This parameter can be NULL. Returns: Zero on error, otherwise the number of bytes written in the MultiByteString buffer. Or the number of bytes needed for the MultiByteString buffer if MultiByteCount is zero.
