Validating user's UTF-8 name in Javascript

Question

I am using the following JavaScript regexp to validate users First and Last names

var regexp = /^((?=[a-z \']).)+$/i;

var val1 = "Normal Text' Compromised";       // true
var val2 = "UTF Text' Połącz Słońce w Mózu"; // false  <---- UTF-8
var val3 = "Illegal char: Blac & White";     // false

example at: http://jsfiddle.net/PR4T2/1/

Question:

Is there any way to make the regex " UTF-8 insensitive " in order to let users use UTF characters ?

I know that UTF is not supported in JS validation yet but I was wondering if there is any workaround. I also do not want to exclude all illegal characters manually like:

var regexp = /^((?![0-9\~\!\@\#\$\%\^\&\*\(\)\_\+\=\-\[\]\{\}\;\:\"\\\/\<\>\?]).)+$/;

---

Edit:

Criteria are characters: az, space, \\, ' and any other UTF char that can be found in user First/Last Name like here .

I'm looking for something more general like \\p{xx} sequencer in PHP
