Summary: GetShortPathName returns incorrect result for baltic 8.3

Initial Comment:
GetShortPathName() returns incorrect result for 8.3 baltic file names. The returned value still contains baltic symbols although it must not.

For "õ2345678.txt" it returns "õ2345678.txt" (should be "234567~1.TXT)
For "õ23456789.txt" it returns "234567~2.TXT" (correct)

To reproduce the bug please run reproduce.bat from the archive attached. (Baltic file names should be preserved with 7zip I believe.)

Python 2.7.3, Russian Windows 7 32 bit, PyWin32 ver. 217

(Sorry, I could not find how to reopen a bug at SF.)

Message:
pywin32 is just a thin wrapper around the windows function, so I believe
that the Windows implementation of GetShortPathName is what you believe is
wrong.

Note that the MS docs say:

* If the specified path is already in its short form and conversion is not
needed, the function simply copies the specified path to the buffer
specified by the lpszShortPath parameter.

* Use any character in the current code page for a name, including Unicode
characters and characters in the extended character set (128–255), except
for [some special chars]

So I think that the first example is already a valid short name.  I'm
afraid you probably need to demonstrate that calling GetShortPathName some
other way (ie, not via pywin32) is returning a different value than when
calling it via pywin32 before I can consider it a pywin32 issue.

I didn't know someone could disable short file names. Anyway files on my
computer are accessible via short names.

Message:
I get the expected result for both files.  If you have short file names
disabled, it's possible to have files that do not have an 8.3 name.
