As long as you are only doing web things with HTML Ruby and Rails are doing well with Arabic / Hebrew languages. As soon as you want to export that data into lets say an image or a pdf you need to reorder the UTF-8 string with a so called "bidi" algorithm.
Has anyone implemented this in Ruby? Or exists a wrapper for Pretty Good Bidi Algorithm http://crl.nmsu.edu/~mleisher/ucdata.html or fribidi (http://fribidi.freedesktop.org/wiki/) ?
