suspicious characters detecter/remover

[DenuxPlays]

New feature motivation

To detect differences between amazon.com and аmаzon.com. (and similiar)

New feature description

Find suspicious characters (like invisible character, cyrillic character).

New feature implementation

I know that symfony has a constraint for this but I am not familiar if there is something similiar in the js world, but I pretty sure there is as there is an npm package for everything.

@DenuxPlays interesting (and useful) idea - I've never heard of this.

• Source code is here
• It seems to use PHP'S native Spoofchecker class under the hood
• Spoofchecker itself apparently uses (C?) ICU library

I suspect that this would be extremely hard to port to client-side JS. They do have a list of "confusables" though - this could be used to create a JS library with similar functionality:

I think this feature is out of scope for string.is, but if anyone has any suggestions on a way to approach this without too much work I'd be keen to hear them!
