For equal strings you should get a match:

>>> re.compile("Zäöü", re.IGNORECASE).search("yadda zäöü yadda")
<_sre.SRE_Match object at 0x401e0a68>
>>> print _.group()
zäöü

For case ignorance your best bet is unicode:

>>> re.compile(u"äöü", re.IGNORECASE|re.UNICODE).search(u"ÄÖÜ")
<_sre.SRE_Match object at 0x401e09f8>
