New submission from Alexey Shamrin <[EMAIL PROTECTED]>: In the process of trying to use optparse with russian messages, I found several problems with gettext and unicode handling:
1. optparse.OptionParser.error function doesn't work with unicode argument 2. optparse doesn't work when its error messages are gettext-translated 3. optparse fails running 'prog.py --help > out.txt' with unicode help (at least on my system: Windows XP, Russian) I have attached a file demonstrating these problems: test_optparse.py. You can run it either using nose[1] or directly, manually uncommenting test_* functions one-by-one.
