Arabic keyboard layout missing ( لا ) symbol

Binary package hint: xkeyboard-config

Hi there

I had this problem since Ubuntu 8.04, it affects 8.10 too

Using the default Arabic keyboard layout, when pressing the button for the symbol لا nothing happens
so i have to press G/ل and then H/ا to write it, because لا = ل + ا

The same thing happens with لأ لآ لإ

لأ = Shift + G

لآ = Shift + B

لإ = Shift + T

I think most of Arab users are familiar with this bug, and proprietary software like Windows
 shouldn't be any better at localized and Arabic support than this great FOSS community.
