Hi !

It seems to be I found a solution. A little tricky, but it is working:
#####################################################################
import sys,os
from sys import argv as sysargv

UFN=u'%s\\xA\xff'%os.getcwd()
if os.path.exists(UFN):
     os.remove(UFN)

f=open(UFN,'w')
f.write('%s\n'%('='*80))
f.close()

from ctypes import windll, create_unicode_buffer, sizeof, WinError
buf=create_unicode_buffer(512)
if windll.kernel32.GetShortPathNameW(UFN,buf,sizeof(buf)):
     fname=buf.value
     #import win32api
     #dfn=win32api.GetShortPathName(name)
     #print dfn
else:
     raise
shortpath,filename=os.path.split(fname)

import win32file
filedatas=win32file.FindFilesW(fname)
fd=filedatas[0]
shortfilename=fd[9] or fd[8]

shortfilepath=os.path.join(shortpath,shortfilename)

print [UFN]
print shortfilepath

f=open(shortfilepath,'r')
print f.read()

sys.exit()

But I don't understand: why the shortpathw not convert the filename too 
(like dir) ?


Thanx for help:
