Invalid regular expression - Invalid property name in character class

Question

I am using a fastify server, containing a typescript file that calls a function, which make sure people won't send unwanted characters. Here is the function :

const SAFE_STRING_REPLACE_REGEXP = /[^\p{Latin}\p{Zs}\p{M}\p{Nd}\-\'\s]/gu;
function secure(text:string) {
  return text.replace(SAFE_STRING_REPLACE_REGEXP, "").trim();
}

But when I try to launch my server, I got an error message : "Invalid regular expression - Invalid property name in character class".

It used to work just fine with my previous regex :

const SAFE_STRING_REPLACE_REGEXP = /[^0-9a-zA-ZàáâäãåąčćęèéêëėįìíîïłńòóôöõøùúûüųūÿýżźñçčšžÀÁÂÄÃÅĄĆČĖĘÈÉÊËÌÍÎÏĮŁŃÒÓÔÖÕØÙÚÛÜŲŪŸÝŻŹÑßÇŒÆČŠŽ∂ð\-\s\']/g;
function secure(text:string) {
  return text.replace(SAFE_STRING_REPLACE_REGEXP, "").trim();
}

But I have been told it wasn't optimized enough. I have also been told it's better to use split/join than regex/replace in matter of performances, but I don't know if I can use it in my case.
