Function Reference


Converts a UTF-16 (wide character) string to a multibyte string

#include <WinAPIConv.au3>
_WinAPI_WideCharToMultiByte ( $vUnicode [, $iCodePage = 0 [, $bRetNoStruct = True [, $bRetBinary = False]]] )


$vUnicode String, DllStruct or Pointer to a byte array structure containing Unicode text to be converted
$iCodePage [optional] Code page to use in performing the conversion:
    0 - The current system Windows ANSI code page
    1 - The current system OEM code page
    2 - The current system Macintosh code page
    3 - The Windows ANSI code page for the current thread
    42 - Symbol code page
    65000 - UTF-7
    65001 - UTF-8
$bRetNoStruct [optional] Flags that indicate whether to return a String/Binary or a DllStruct (default True : String/Binary)
$bRetBinary [optional] Flags that indicate whether to return a Binary String or a String (default False : String)

Return Value

Success: A string/binary or a DllStruct containing a multibyte string/binary.
Failure: Sets the @error flag to non-zero, call _WinAPI_GetLastError() to get extended error information.


Maps a UTF-16 (wide character) string to a new character string.
The new character string is not necessarily from a multibyte character set.

The $bRetBinary flag is designed for users of multi-byte codepages and forces the function to return a 0-terminated binary string or a struct containing it depending on $bRetNoStruct.

The $bRetNoStruct flag determines if the function should return only the string/binary or the entire struct.
