Arabic Keyboard Swapping Language:

Convert keyboard language between English/French and Arabic programmatically. This function can be helpful in dual language forms when users miss change keyboard language while they are entering data.

If you wrote an Arabic sentence while your keyboard stays in English mode by mistake, you will get a non-sense English text on your screen. In that case you can use this method to make a kind of magic conversion to swap that odd text by original Arabic sentence you meant when you type on your keyboard.

Please note that magic conversion in the opposite direction (if you type English sentences while your keyboard stays in Arabic mode) is also available, but it is not reliable as much as previous case because in Arabic keyboard we have some keys provide a short-cut to type two chars in one click (these keys include: b, B, G and T).

Well, we try to come over this issue by suppose that user used optimum way by using short-cut keys when available instead of assemble chars using stand alone keys, but if (s)he does not then you may have some typo chars in converted text.
