IE Javascript Regex bug Fails Jquery trim

If you are using $.trim(astring) in IE, even in IE8, the leading and trailing spaces are not trimmed at all.

This is due to a bug of javascript regex implementation by ie not including \xa0 into \s.

The code of jquery trim is

trim: function( text ) {
		return (text || "").replace( /^\s+|\s+$/g, "" );
},

As it is rightly pointed out by jquery trim api page, in ie you have to do like this to trim spaces:

astring.replace(/(^[\s\xA0]+|[\s\xA0]+$)/g, '');

I am afraid this is not the only place we will get the problem, in fact all regex ‘\s’ will fail in IE.
