About this package

Unicode homoglyphs can be a nuisance on the web. Your most popular client, AlaskaJazz, might be upset to be impersonated by a trickster who deliberately chose the username ΑlaskaJazz. (The A is the greek letter capital alpha), _(*3)

This is a complete port of the Python library vhf/confusable_homoglyphs to PHP. I found myself needing its functionality after reading this article by James Bennett on validating usernames and how django-registration does so., _(*4)

A huge thank you goes to the Python package creator Victor Felder and its contributors Ryan Kilby and muusik; without their work this port would not exist., _(*5)
