They get the commnd line in UTF-16 anyway. Ok, I found a problem. Assuming the argument is a valid filename in UTF-8 encoding, as it's the default when using LANG=C. If we try to convert this string using the ANSI codepage, the native child process will get a malformed filename as argument. Looks like always using the ANSI codepage is not exactly a good solution...
