font in open firmware

[Yoshinori K. Okuji]

I have implemented a new function getcharwidth in the terminal interface. I 
updated all terminals for PC but didn't ofconsole. This is only because I 
don't know how it behaves precisely.

According the standard, the default font seems to be implementation-dependent. 
There is an attribute "character-set", but I don't know if this is used.

So, in reality, what kind of font is used in Open Firmware? Does it only 
contain US-ASCII or is it like the VGA font? For now, ofconsole does not map 
any Unicode character to another character, but does this work well?
