Range out of order in character class on regex

I am trying to create a regex class from this pattern like this:

let regex:RegExp = RegExp(/^(?:[\x{c0}-\x{1ff}a-zA-Z\'-]){2,}(?:\s[\x{c0}-\x{1ff}a-zA-Z\',.-]{2,})+$/, 'iu');

I took it from an earlier project I did with PHP and I know it works there. However, it does not work here:

SyntaxError: Invalid regular expression: /^(?:[\x{c0}-\x{1ff}a-zA-Z\'-]){2,}(?:\s[\x{c0}-\x{1ff}a-zA-Z\',.-]{2,})+$/: Range out of order in character class

My environment runs on nodejs 6.

Can anyone help me fix this? thanks.

Try removing bits of the regex until it compiles, the last one you removed is the one that broke the regex – JGNI Aug 16 '18 at 14:15
Try it like `/^(?:[\u{c0}-\u{1ff}a-zA-Z'-]){2,}(?:\s[\u{c0}-\u{1ff}a-zA-Z',.-]{2,})+$/u` – Wiktor Stribiżew Aug 16 '18 at 14:17
