I'd use:

a = widget.get().encode(userEncoding, 'replace')

This will replace any character in the string that is not in userEncoding by a 
'?', but it should never raise an exception (if I'm not mistaken...). And if 
your user can type a character, it should be in his/her local encoding, so 
replacements shouldn't occur.
