Unicode Regular Expression won't work ??

HEEEELP ME!

I can't make javascript to validate username form field with unicode characters (charset=utf-8).

PHP that works well on server side:

$legalChars = "/\p{L}|\p{Pc}|\p{N}/"; // allow letters, numbers and underscores
$legalCharsCount = preg_match_all($legalChars,$strng,$blb);
...

JavaScript that drives me crasy:

var error = "";
var illegalChars = /\p{L} \p{Nd}/; //I tried also: / :Lu | :N / and similar expressions without result.
if (illegalChars.test(strng)) { //tried also .match and .seach combinations
error = "The username contains illegal characters.\n";
}

Is ther anyone out-there to know what it is all about ??

Many thanks in advance.

I haven't dabbled with regex and JavaScript much, but you'll need quotes around the illegalChars variable. Hope it's as simple as that!

Uf, do not work
Actualy, javascript won't accept the reg.ex if it is enclosed in quotes
