So, I think that, in arabic script, users like to have <backspac> to delete
the previous key typed. This is the same as Thai/Indic/Korean/Vietnamese...
One difference in arabic is that those base letter with diacritic
(U+0622..U+0626) will be treated as a single letter and that is also typed
by one key stroke. The <backspace> algorithm still works with those letters
because they have their own codepoints. <backspace> algorithm is just removing
one codepoint from logical stream...
For lam+alif case, <backspace> algorithm (if it's just removing one logical
codepoint before the current cursor) will just remove "alif" first and this
should satify arabic users as well...., I guess.....
