Hi Thomas

 Thanks a lot. It worked. I have similar problems in the module
os, when using the os.listdir() function. Any ideas about it ?

 Here is the error report:

  "LookupError: no codec search functions registered: can't find encoding"

  I am passing a unicode string to the function os.listdir(dir) which works
well in normal python interpreter.

Thanks & Regards,

Anand
