Regular expression not matching specialist unicode characters

Question

I'm trying to match unicode regular expression but somehow the \p{L} wont work.

<script>
    var input="teëst";
    var re = /^[a-zA-Z-. \pL]{2,32}$/;
    var is_valid=input.match(re);
    if(is_valid){
        document.write('Regularexpression valid');
    } else {
        document.write('Regularexpression invalid');
    }
</script>

Workaround:

    var re = /^[a-zA-Z- \u00c0-\u017e]{2,32}$/;

Answer 1

My google search on javascript online regular expression check brought me to regex101.com and this validated my regexp so during the creation of this question I thought I was doing something wrong elsewhere in the code. Points out unicode is not supported yet.

Workaround:

    var re = /^[a-zA-Z- \u00c0-\u017e]{2,32}$/;

Answer 2

You can use:

var re = /^[a-zA-Z\u00C0-\u017F-. \pL]{2,32}$/;

It uses unicode matching, See here

Answer 3

Try with this regular expression:

var re = /[^\x00-\x7F]+/;
