Hello,

I have just had a request from a user who wants to have Arabic Language 
Support and to be able write Arabic script from a US English.  Is this 
fully supported in CentOS?

The user is convinced that he needs a newer version on gnome based on 
this post
http://library.gnome.org/misc/release-notes/2.28/#rndevelopers.epiphany

But I am going to try installing a system with Arabic Language Support 
and see how it goes.  Would anyone using Arabic recommend using SCIM?

Thanks for any advice you can offer
