Summary: GetShortPathName() fails for 8.3 baltic file names

Initial Comment:
If a 8.3 file name containing at least one baltic character is given to GetShortPathName(), it fails with exception. It does not fails on long file names:

Traceback (most recent call last):                                                                             
  File "D:\workspace\investigations\audio-hash\invest\GetShortName-bug\bug.py", line 10, in <module>           
    print win32api.GetShortPathName(file)                                                                      
  File "C:\Python\27\lib\encodings\cp866.py", line 12, in encode                                               
    return codecs.charmap_encode(input,errors,encoding_map)

Message:
It appears the problem here is actually with "print" attempting to use the
cp866 encoding when printing to your terminal.  GetShortPathName returns
the same type of object as its param (eg, if you pass a byte string, it
returns a byte string) and this string is failing to print as it isn't
encoded as cp866 (it will be encoded as MBCS).

You can confirm this by changing your code to something like:

x = win32api.GetShortPathName(file)
print x

you should then see clearly the exception is from the print, not from
win32api.  Probably the best solution is just to ensure "file" is a unicode
object before passing it to win32api.GetShortPathName.  Please reopen this
bug and add further information if you believe this is not the case.
