OemToChar is equivalent to calling MultiByteToWideChar with CP_OEMCP (code
page 437) as the source code page when converting to Unicode characters.
(i.e. if UNICODE is #defined so you're really calling OemToCharW).

When working with single-byte characters (UNICODE not defined, so you're
really calling OemToCharA), the function does a simple 1 for 1 replacement
of characters in the source set with characters from a mapping table.
Multibyte characters will not be converted correctly in this case.

Sounds like you need to be working in Unicode.
