Convert Unicode to double ASCII letters in Python (ß -> ss)

Question

Some Unicode characters can also be written as two ASCII letters (e.g.: ß -> ss, å -> aa). Is there any way to convert these in Python, without having a list with all of them?

LATER EDIT:

This kind of conversion is done by a lof of websites, including Stackoverflow (url from this page was converted), and Twitter. I'm curious how they do it.

Answer 1

There are no universal rules.

You could try unidecode module to transliterate Unicode text to ASCII.
