I am trying to test a regex on a string with locale letters. Although I have been browsing stackoverflow and googling for quite a while now, I can't seem to figure out why it's not working.

There are 6 locale letters the regex would need to "recognize". Those are čČšŠžŽ.

I have tried various things. I tried just using the "locale words". This didn't work.

var regexList = [/\bžaba/gmi, /\bčešnje/gmi]
regexList[0].test("žaba") //returns false

The next thing that looked promising was adding/merging a "caron" to the basic ascii letters, shown in this example. This was not a valid regex

var regexList = [/\b[zZ]\u02C7aba/gmi, /\b[cC]\u02C7es\u02C7nje/gmi] //invalid regex

While the 1st example works in regex101 it doesn't work in practice. Any help or references would be most welcome.

Other questions that I found useful can be found here and here, but they do not directly relate to my problem.

Thank you

The problem here is that the word boundary (\b) does not recognize your unicode characters. See here for a workaround: https://stackoverflow.com/a/10590516/10551293.

While besides the \byour regex works with literal unicode characters, you could use unicode code points: /\u017eaba/. Code points have the advantage that they clearly state what character is to be matched, which is especially helpful for characters that have a similar appearance or look identical to regular ascii characters.
