Ok, you convinced me. Implement that in a way that Alexandre will deem 
fit for commit, and I won't object too loudly. I do believe that you 
will not succeed with the first part, however.

True, but irrelevant.

Forget that. How would you run that under Windows? As far as I know, you 
can't do it there either. Coming from a country where a large portion of 
the population are native Russian speakers in a country where the 
dominant language is Hebrew, I'm pretty sure that I'd hear about it if 
it were possible.

Yes. That's because they either use the Unicode interface, or implement 
their own rendering engine.

In short, I think what you're trying is impossible under Windows. I can 
also see some immediate implications to trying to do it in Wine. If it's 
important to you, you're welcome at it. It will not enter my personal 
todo list, however.
