How to detect the language of a given text

In my Rails 3 application, users may write messages in forum. I would like to identify what the language is for a given message. I'm interested in English, Russian, and Hebrew languages. Is there any built-in library in Ruby/Rails for such a task? If not, any ideas will be appreciated.

Since you're concerned with languages with different character sets you could dig up the character codes that are predominantly in your strings. You could then see if they fall into the code sets that represent hebrew / cryllic characters.

You can use the api provided by google to guess it with google translate.

See here for documentation : http://code.google.com/apis/language/translate/v1/using_rest_langdetect.html
