Normality is a Python micro-package that contains a small set of text normalization functions for easier re-use. These functions accept a snippet of unicode or utf-8 encoded text and remove various classes of characters, such as diacritics, punctuation etc. This is useful as a preparation to further text analysis.

# coding: utf-8
from normality import normalize, slugify

text = normalize('Nie wieder "Grüne Süppchen" kochen!')
assert text == 'nie wieder grune suppchen kochen'

slug = slugify('My first blog post!')
assert slug == 'my-first-blog-post'

Read the source code, it's twenty lines of stuff.
