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, Vafa Khalighi
