As a starter, try this unicode page:
http://perldoc.perl.org/perlunicode.html

Also of interest could be, which shows Arabic encodings:
http://unicode.org/charts/PDF/U0600.pdf Anyway you are going to maybe need to know what kind of dialect of Arabic you are using.

If you want a decent translation, you are going to need to display this Arabic stuff and have somebody who speaks arabic translate it for you. This is very difficult as usually there are multiple meanings per word. So you have a huge problem to solve there! I don't know of any Perl module that can do this. Although there may be some kind of say Google web gizmo that does translations and then we are into a a CGI type of application which can be done in Perl.

If you can get the problem down to "hey, this set of bits that mean a word in Arabic, need to get transformed into this set of bits that are english characters", then that job can be done.

Read above link about unicode . I don't how to be of more help right now.
