Lost you there. We are currently using ICU precisely because it does 
have UTF-16 support.

Lost you there again. There is no dependence of BiDi on collation, or we 
would use ICU for a lot more than only BiDi. ICU is an entire Unicode 
solution, and does have all of those things.

Seriously, I don't see anyone here volunteering to maintain the BiDi 
code, and I don't have the resources to chase Unicode around. I really 
think using an external library is the right thing to do.
