Hello, base,

I spent 5 years doing multilingual DTP for a translation agency... I can't stress this enough: Arabic is very, very tricky to typeset... And MS Word is not the best program in the world for working with Arabic! You will try to select a character on the right end of a line and will end up selecting the one on the left side... Periods will not behave the way you expect them to... I could go on and on. For any lengthy text, the best thing to do is to send the job to a designer or production artist who knows and works with Arabic text on a daily basis... There are just too many things that can go wrong if you try to do it yourself. And Arabic typesetters are scarce, so they can charge you a bundle!

Florian already mentioned InDesign ME... There is also Illustrator ME... These versions of the Adobe apps were made to deal with right-to-left typesetting (i.e., Arabic, Hebrew). If you have to do the job yourself, try to use one of these programs... Using a Western version of MS Word will just give you non-stop headaches. I kid you not.

thanx a lot man,
is a beautifull language to see, let say being able to work with it.
best greetings
base
