The range caps at FFFF hex because JavaScript only supports Unicode's Basic Multilingual Plane. It might be more useful to kill everything outside the 128 US-ASCII characters. That would be <code>replace(/[\u0080-\uFFFF]+/g, "")</code>. @Jason, I think you’re confusing your terminology a little, but to remove all Unicode code points higher than 255 decimal (FF hex) in JavaScript you could use replace(/[\u0100-\uFFFF]+/g, "").

Also, reserved XML characters are present on most keyboards and might need separate, special handling. I would recommend that you refer to regex <a href="http://www.regular-expressions.info/charclass.html" rel="nofollow">character class</a> documentation, the Windows charmap application, and perhaps a regex forum like <a href="http://regexadvice.com" rel="nofollow">regexadvice.com</a>.

I work with XML and people have been copying and pasting to the text areas from Microsoft word and these stupid special characters that Microsoft has make my programs fail I need a string that contains a-z A-Z 0-9 the typical special characters that u can type from the keyboard and thats it nothing else any one can give me some help with this would be great. look this is great and its just what I need for my stuff.. unfortunately I’m having problems with symbols.
