This system is not perfect and a bit confusing albeit convenient and accessible. I'm thinking going for a diacrtics-based system for formal transliteration in lation like for example: - âadel == عادل (fair) (noun) - ĥaled == خالد (eternal) (noun) and so on and so forth but the problem is most computer keyboards used in by native Arabic speakers are US compatible and those letters are not accessible and even on mobile devices, it's a bit inconvenient to type those letters.
