regexp doesn't proper test

Question

I have a regex:

/^([\u00c0-\u01ffa-zA-Z]+['-]{0,1}){3,30}$/

Which means I can use 3-30 given characters, but my upper limit doesn't work. Here is the example with 35 characters string:

/^([\u00c0-\u01ffa-zA-Z]+['-]{0,1}){3,30}$/.test('TXTGWDRWHWTXTGSXYEWGUAHZXQCWDRWHWTX');

And it returns true, but should returns false

So you want the total length to be from 3-30 characters with an optional quote or dash at the end ? — , Aug 31 '17 at 21:30
The regex has nested quantifiers; the `+` gives the inner subpattern an unlimited length. — Ruud Helderman, Aug 31 '17 at 22:03

Each one of these length questions are different.
No two are alike.

For this one I'd suggest

/^[\u00c0-\u01ffa-zA-Z]{2,29}[\u00c0-\u01ffa-zA-Z'-]$/.test('TXTGWDRWHWTXTGSXYEWGUAHZXQCWDRWHWTX');

Which, gives a total of 3-30 characters.

console.log( /^[\u00c0-\u01ffa-zA-Z]{2,29}[\u00c0-\u01ffa-zA-Z'-]$/.test('TXTGWDRWHWTXTGSXYEWGUAHZXQCWDRWHWTX') );

Output

false
