Once i wrote about how the new service from google called ta3reeb can help convert Roman characters to Arabic words. Now Microsoft has just came up with a competitor called Microsoft Maren which allows you to type Arabic in Roman characters (Romanized Arabic, Arabizi, Arabish or Franco-Arabic) and have it converted on the fly to Arabic script.Maren integrates seamlessly with Windows and works in most Windows applications and websites.
Now as you can see from the video the program is coded with Egypetian words, so i dont know how well it will work with Kuwaiti Arabic. Will it do the job or not? you will be the gudge i guess.
