; Module Name:
;
;    nlstrans.asm
;
; Abstract:
;
;    This module implements the function to translate from Unicode
;    characters to ANSI and OEM characters.  The translation is based on
;    the installed ACP and OEMCP.

;     MultiByteString - Returns an ansi string that is equivalent to the
;         unicode source string.  If the translation can not be done
;         because a character in the unicode string does not map to an
;         ansi character in the ACP, an error is returned.
;
;     MaxBytesInMultiByteString - Supplies the maximum number of bytes to be
;         written to MultiByteString.  If this causes MultiByteString to be a
;         truncated equivalent of UnicodeString, no error condition results.
;
;     BytesInMultiByteString - Returns the number of bytes in the returned
;         ansi string pointed to by MultiByteString.
;
;     UnicodeString - Supplies the unicode source string that is to be
;         converted to ansi.
;
;     BytesInUnicodeString - The number of bytes in the the string pointed to by
