import unicodedata

def uncombine(char):
    chars =3D unicodedata.decomposition(unichr(ord(char))).split()
    if not chars:
        return [char]
    return [unichr(int(x, 16)) for x in chars if x[0] !=3D "<"]

for char in "Fran=E7ois":
    print uncombine(char)

[u'c', u'\u0327']

(to go the other way, store all uncombinations longer than one
character in a dictionary)
