This is less of a question of how, and more, what is this called? I had a module installed in npm a while ago that would take a string and remove any emojis, bad characters, or anything like that and replace them with a filename-safe text version instead. For example "$" would become "dollar", "/" would become "slash" etc. The process of doing this action had a name itself but I can't remember what it's called and google searching has done me no good. Thanks!
