Hi,
depending on the circumstances, there are probably more sophisticated
ways (what does "fix the characters" mean?), but do you maybe think
something like:
>>> u"aáčbüêcîßd".encode("ascii", "ignore")
'abcd'
? It might be important to ensure, that you won't loose any useful
information; where are the unexpected characters coming from, or
couldn't it possibly be fixed in that source?

hth,
