It seems to me that Arabic is lacking two characters when using Eastern 
Arabic digits, not Western Arabic. Unicode allowing the m² and m³ unit 
notations, these should be implemented in any script using the same 
notation. Not the whole UCS, just these two, like Arabic per cent. Or do 
you have use cases in Arabic where superscript is used as an 
abbreviation indicator?

I don’t share the view according to which superscript is arbitrary in Latin.
There is a medieval tradition of superscripting. If it is in Arabic, then it 
would be limited to these two missing digits. Many many symbols were 
encoded for Arabic, notably mirrored arrows, so adding these two is quite
straightforward.

Sad that Arabic ² and ³ are still missing.
