We have to match all language characters like chinese, german, spanish in addition to english language characters except special characters lik开发者_开发问答e *(). I am struck on how to match those non-latin characters. Any help appreciated.

If your regular expression engine can match Unicode categories, the regex \p{L} matches any letter in any language. JavaScript does not support Unicode categories. If you use XRegExp with the Unicode plugin, then you can do it like this in JavaScript:

XRegExp('^\\p{L}+$').test($input)

This will return true if $input consists of one or more letters and nothing else.

Unluckily there isnt much support for unicode for unicode regular expressions in javascript

I've used bits of XRegExp for this kind of thing and it's worked as expected so far. There's Unicode plug-ins here: http://xregexp.com/plugins/
