[Bug 26632] New: MultiByteToWideChar with MB_ERR_INVALID_CHARS doesn't fail for some code points.

http://bugs.winehq.org/show_bug.cgi?id=26632

Summary: MultiByteToWideChar with MB_ERR_INVALID_CHARS doesn't
                    fail for some code points.
           Product: Wine
           Version: 1.3.17
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Created an attachment (id=33899)

test MB_ERR_INVALID_CHARS

I ran the attached source code in both Wine and Windows XP environments. In
some codepages, inclueding Japanese (CP932), the result doesn't match.

For instance, Japanese Windows marks `X' (conversion fail) for 0xA0, 0xFD, 0xFE
and 0xFF. But Wine (LANG=ja_JP.UTF-8) marks `o' (OK) for them.
This only happens when I pass MB_ERR_INVALID_CHARS for MultiByteToWideChars.
