OK, should I write a patch for the logging module to convert the string to
unicode before applying lower()? So far that seems like the way to go.

Maybe this could also be explained in the documentation:

http://docs.python.org/lib/node323.html

I don't think I've seen it in the locale documentation that locale settings do
not affect unicode strings, and that particular page says

If, when coding a module for general use, you need a locale independent version
of an operation that is affected by the locale (such as string.lower(), or
certain formats used with time.strftime()), you will have to find a way to do
it without using the standard library routine.

Unicode might be a perfectly acceptable suggestion for others too.
