But that doesn't change to reflect the locale, which I thought was the
point of what you asked.

That did occur to me as a possible problem.  Did we mention converting
your app to all-unicode-all-the-time?  Oh yes, I think you did.  Try
it: it might not be as hard as you think.  I was surprised how easy it
was to convert pyrepl.
