No, Thank you for using it :) hope its helping you :)

I see up there that you might be calling doShape yourself ?
why not let doBidi() do it ?
if thats the case then you have to copy the original string
to the destination string first. doBidi() takes care of that
if you pass applyShape == 1.
4024 probably was there before the doShape() call.

I know that copying the string can be dodged by copying
each char in the doShape() iterations, but I had a motive for
that which I cant seem to remember, so if I cant remember it by
next week I'll move the string copying thing inside doShape()
and you wont have to do it yourself.

BTW, whats that QString you're using ? take a look at this...

[code]
/*
 * Datatype Extension Macros
 */
#define BLOCKTYPE unsigned short*
#define CHARTYPE unsigned short
#define GETCHAR(from,i) from[i]
[/code]

at the begining of minibidi.c you'll find these macros, if you can fit
QString's usage into these macros, you can call doBidi directly on a
QString, i.e doBidi will use the QString and you wont have to copy to
another array. is there an online doc for it ? something like an MSDN
page or doxygen ?

Im on the developer list in digest mode, so my replies might
be 1 day late :(
