Unicode strings with non-ascii chars in generate a
UnicodeEncodeError

  File "/usr/lib/python2.3/optparse.py", line 1370, in
print_help
    file.write(self.format_help())
UnicodeEncodeError: 'ascii' codec can't encode
characters in position 200-202:
+ordinal not in range(128)

I'm subclassing OptionParser and adds the following
method to get it to work. Should something like this be
done for python 2.5?

def print_help(self, file=None):
    if file is None:
        file = sys.stdout
    file.write(self.format_help().encode(file.encoding,
'replace'))

Fixed pretty much as suggested in upstream Optik repository:
r520.

(However, I had to use
  getattr(file, 'encoding', sys.getdefaultencoding()) 
to maintain compatibility with Python 2.0 .. 2.2).

No doc changes, since help generation isn't really
documented all that well anywhere.  ;-(

Fixed on Python trunk: r46861.
