`clearSimilar(string)`

Usecase

This is used internally by our team in our Discord bot and similar applications with the purpose of removing sneaky characters that are often abused by bad actors to bypass a filter or make it hard to contact them. Someone could bypass a word filter by using these special characters. This soloves that issue!
