This is fixed by your change to w32term.c. Now only the initial display 
corruption is a problem, so I will debug that and see if I can 
differentiate between errors that mean the font cannot use glyph codes, 
and other errors that only apply to specific characters, which we could 
indicate by treating that character as missing in the font.
