I always thought D supported Unicode with the goal of going 
forward with it while C was stuck with ASCII:

"The D programming language has already driven stakes in the 
ground, saying it will not support 16 bit processors, processors 
that don't have 8 bit bytes, and processors with crippled, 
non-IEEE floating point. Is it time to drive another stake in and 
say the time for Unicode has come? "

Have you changed your mind since?
