Ok, accepted. Not only by me, but also by Bidi's maintainers.

I'm currently shifting my efforts to creating the required 
infrastructure in fribidi for supporting all of our current and future 
needs (UTF-16 included). Once that's in fribidi, I trust depending on it 
will not be considered a problem, right?

Ouch :-(. Actually, there is a lot of interest in people wanting Wine to 
support Bidi (or at least, Hebrew). This can be seen from the comments 
on any of the many articles in recent press about Wine, Lindows etc. 
Sadly, this did not create a movement of developers, true (unless you 
count yours truely as a "movement").

Point taken and observed. I'll make sure fribidi has, at least, the 
final package dependancy (I don't know, yet, whether packagers will 
choose to package fribidi-utf16 in a different package), and I'll 
resubmit. I have, pretty much, a guarantee from Behdad that the required 
changes will be supported.

Time to direct efforts torwards a better fribidi design.
