So %3F == '?', which is probably because we have a
"unicode_str.encode(LANG, errors='replace')" somewhere in there.

So instead you could have the test alonge the lines of:

subject = urllib.quote(str.encode(osutils.get_user_encoding(),
                       'replace'))

Otherwise it sounds like it will fail if you have other encodings anyway.

And I think if you use urllib.quote() we can make it work under any
LANG, even one that gives iso-8859-1 (like LANG='en_US' rather than
LANG='en_US.UTF-8').

Thoughts?

I certainly still consider it worthwhile, though in the end it matters
mostly what *claws* would accept given a different LANG on the system.
