I have a multilingual website (Chinese and English).

I like to validate a text field (name field) in javascript. I have the following code so far.

var chkName = /^[characters]{1,20}$/;

if( chkName.test("[name value goes here]") ){
  alert("validated");
}

the problem is, /^[characters]{1,20}$/ only matches English characters. Is it possible to match ANY (including unicode) characters? I used to use the following regex, but I don't want to allow spaces between each characeters.

/^(.+){1,20}$/
javascript regex unicode character-properties
