Regex targets multiple letters as one match, causing problems in my code

Question

I'm trying to get all letters in a string. But, sometimes, it matches two letters as one match, causing problems.

I think these strings that I'm using have invisible characters in them that are messing things up. Here is one of the strings I was using: "s͏uc͏͏ce͏͏s͏s". If you put that in https://regexr.com/ with ([a-zA-Z])+, it will mark "uc" and "ce" as individual matches. How do I get it to match each character as an individual?

example of problem

so I'm assuming if I remove all of those Unicode junk it will work properly? How do i do that? — Bop It Freak

Take away the +

The + is a way of denoting one or more elements fitting your sequence constitutes one expression

With what are you trying to replace the letters?

I am using regex.

The replace function will replace all sequences meeting the definition of your regex.

The whole point of this really is to delete that stupid invisible unicode character, as sln pointed out.
