How to catch all special characters during string matching?

Question

Is there any way to be able to catch all exceptions when doing string matching? For example if I have a string,

print("red" =="red" )
# evaluates to True

However,

print("Rεժ" == "red")
# evaluates to False

What I would like is to be able to catch all the special cases such as the following

print("Rεժ" == "red")
print("RêÐ" == "red")

to be evaluated to be True. The use-case for this is to be able to have some sort of text filtering to be able to catch all the words "red".

As Tomalak and Laurens Koppenol eluded to in the comments, this could be a possible duplicate of other SO questions involving UTF8 or Unicode characters with accent marks, but the following code returned true for me:

import unidecode

accented_string = u'RêÐ'
unaccented_string = unidecode.unidecode(accented_string)
print(unaccented_string.lower() == "red")
