I read "If we have \autoLRdirset, then characters 0 to 127 as LTR  
characters and characters
128 to 255 as RTL characters, will be assumed and based on this the  
direction of the
typesetting will be determined."

First of all, both LTR and RTL characters are far more than 128.

And secondly, there are many characters which are neither LTR nor RTL  
(like the period, exclamation mark, delimiters, etc.). Are you using  
two different periods, two different exclamation marks, etc.? That was  
the Apple approach during the Worldscript era.

Unicode bidi algorithm has be designed to take all these issues into
