py2casefold 0.1.3

py2casefold

Python 3 has str.casefold(). Python 2 doesn’t. py2casefold brings casefolding support to Python 2.

Installation

pip install py2casefold

Usage

>>> from py2casefold import casefold
>>> print casefold(u"tschüß")
tschüss
>>> casefold(u"ΣίσυφοςfiÆ") == casefold(u"ΣΊΣΥΦΟσFIæ") == u"σίσυφοσfiæ"
True

Note that casefold does not normalize the string. Casefolding and normalization are different operations. For more info see http://www.w3.org/International/wiki/Case_folding, and http://www.w3.org/TR/charmod-norm/.

If you are looking for string similarity you will also probably want to consider one of the unicode normalization options (NFC, NFKC, NFD, NFKD) that are available with python’s built in unicodedata.normalize().
