As you have written it, that's not a character, it is a string of length
two. Did you perhaps mean the Unicode character u'\xa0'?

>>> len('u\xa0')
2
>>> len(u'\xa0')
1

Seems to work for me:

>>> c = u'\xa0'
>>> s = "hello " + c + " world"
>>> s
u'hello \xa0 world'
>>> s.replace(c, "?")
u'hello ? world'
