A little bit of explanation: wchar[] is an output range that can accept 
any form of text. When you use `put` on it, it writes to it, AND shrinks 
from the front to allow remembering where it was. So at the end, buf is 
pointing at what is *left* in the buffer.


There may be better ways to do this, but this way will avoid any extra 
GC allocation.
