If you know before hand that you will be using ascii, you can eliminate
the accents, so that you will get the unaccentuated letter (followed by
a question mark if you prefer) instead of a question mark

>>> from unicodedata import normalize, combining
>>> example = u"ähnlich lölich üblich"
>>> normalised =  normalize('NFKD', example)
>>> normalised.encode("ascii", "replace")
'a?hnlich lo?lich u?blich'
>>> eliminated = u''.join(l for l in normalised if not combining(l))
>>> eliminated.encode("ascii", "replace")
'ahnlich lolich ublich'
