A PHP port of vhf/confusable_homoglyphs
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)
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.
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.
This library is compatible with PHP versions 7.3 and above.
Install this library with composer: composer require photogabble/php-confusable-homoglyphs.
Please see the tests for detailed example of usage.
