Ezio Melotti ezio.melo...@gmail.com added the comment:
The problem here is that you are mixing byte strings and unicode.
glob.glob('*.ods') returns a list of strings, so in shutil.copy2(file, 'א') you
are passing two byte strings and everything works fine.
In shutil.copy2(file, u'א') instead,
Adam Matan a...@matan.name added the comment:
Don't you think that shutil should be able to handle mixed data types, for
example byte string as file name and unicode destination directory? This is, in
my opinion, a very common scenario.
Would you consider converting all arguments to Unicode?
Ezio Melotti ezio.melo...@gmail.com added the comment:
I should have added that both 'א' and u'א' work as long as the file names in
the list returned by glob() are ASCII: if u'א' is used they are simply coerced
to unicode.
If there are non-ASCII file names in the glob() list, the copy fails
Adam Matan a...@matan.name added the comment:
Don't you think it should be changed in Python 2.x, so that the ASCII filename
will be automatically converted to to Unicode?

The ASCII filename is already converted to unicode, but in your case the
program was most likely failing with some non-ASCII filename.

Do you think it should be fixed at the module level?

Ezio Melotti ezio.melo...@gmail.com added the comment:
Mixing byte and unicode strings should always be avoided, because the implicit
coercion to unicode works only if the byte strings contains only ASCII, and
fails otherwise.
Several modules -- including shutil, glob, and os.path -- have API
