This is correct. Unicode PUA by default assumes LTR behaviour. Therefore inserting PUA codes in an Arabic string is asking for trouble. > Mete, > I've not test the code point yet.

U+06DF Arabic Small High Rounded Zero can occur on any alef, even when it follows a lam, so it needs to be handled by fonts anyway. t
