It IS only mirrored when surrounded by rtl characters, that was
what I included the nonsense string for.  When not so surrounded,
it, Shift-9 generates ")" /and it is shown as ")"/.   Arabic keyboards 
still have ( printed on 9, so I guess they work majority-rtl (which 
would make sense).

I don't see why. Other apps don't.

9*)4+5(

surrounded:

ثثث9*)4+5(ثثث
- but that was when I typed the expression as if LtR (i.e. hitting 9 
first),  I suspect an arabic person might type

ثثث(5+4)*9ثثث

- i.e. hitting ")" first when transcribing "9*(4+5)".  Then it just 
works I think as above (I'm including a screenshot from icedove just in 
case)

I expect that's in fact what arabic users expect, though an actual 
arabic person might want to speak up...
