I'll try this tomorrow, in the mean time I can confirm that something odd is 
happening in the shaping, I attach a simple program that uses minibidi and 
this is the output (compile with
 gcc qbidi.cpp -L/usr/qt/3/lib -lqt -I/usr/qt/3/include
)
:

: char 0 is 643
: char 1 is 650
: char 2 is 62a
: char 3 is 627
: char 4 is 628
: char 0 is fe8f
: char 1 is fe8e
: char 2 is fe98
: char 3 is 4082
: char 4 is fedb

There's definitely something odd going on with the kasra
