There I found the module unidecode
(http://pypi.python.org/pypi/Unidecode),
and I found it very helpful. Thanks a lot!
So my function normal() now looks like this:
from unidecode import unidecode
def normal (s):
r = s
r = r.strip() # take away blanks at the ends
r = r.replace(u' ', '') # take away all other blanks
r = unidecode(r) # makes the main work
# - see the docu of unidecode
r = r.upper() # changes all to uppercase letters
return r
def compare (a, b):
aa = normal(a)
bb = normal(b)
if aa < bb:
return -1
elif aa == bb:
return 0
else:
return 1
For the "normal" cases, that works quiet perfect - as I want it to do.
For more (extreme) difficult cases there are even limits, but they are
even wide limits, I would say. For example,
print normal(u'-£-¥-Ć-û-á-€-Đ-ø-ț-ff-ỗ-Ể-ễ-ḯ-ę-ä-ö-ü-ß-')
gives
-PS-Y=-C-U-A-EU-D-O-T-FF-O-E-E-I-E-A-O-U-SS-
That shows a bit of what unidecode does - and what it doesn't.

Sorry, I didn't find that.

But even a helpful bystander. Thank You!
