I think that's what is going on. On my cygwin:
$ od -x system.ajf
0000000 fcbd 6100 746c 7836 3031 0000 0000 0000
0000020 0000 0000 0000 0000 0000 0000 0000 0000
0000040 0000 0600 0a00 0000 0000 0c00 0000 0000
bdf2ajf should write things as bytes so hopefully
it's only output problem.

Thanks. I really have very little chance to test things on Unix - your
patch is very helpful.

That's on my schedule for sure.

Actually I would like to find it myself. I don't think it's in
collection of fonts I got. Rockbox works fine though with, say 6x10
chars (except that WPC display is a bit hard to maintain). As you so I
changed most places to take height into account.
I also have a font which is 8x8 but I don't like how it looked.
Notice that I only looked in BDF 2.1, so I don't know if bdf2ajf will
work with BDF 2.2.

Thanks for comments
Alex
