I noticed a bug about unicode bidi in AAT font; the unicode bidi behaviour
in AAT is different to  open type fonts.

WIth AAT font, if you typeset left Persian quote (»), in the output you get
right Persian quote («) and vice versa. These should not be mirrored.
Furthur with opentype fonts, if you type 1\hskip0pt.2, then you get 2.1 but
with AAT font, you get .21. There are several other things which I do not
remember yet but will let you know about them.

So is this a bug?

Best wishes,
