Comment 9 for bug 1729695

Take a look at the message in duplicity-team called "Help with unicode
branch (for Python3 support)".

It turns out that uexc() is using ufn() which is calling
sys.getfilesystemencoding(). We may have a fix, not implemented yet, for
sys.getfilesystemencoding() returning 'ascii' or None when called in a
detached process. Would like your thoughts on that.
