Thanks Derek,

I'll have a play with that later today. 
It will be interesting to see if I can use that for double-byte fonts.

Meanwhile, I found that there are a few kanji fonts available in
bdf format, which is far easier to understand than the example to 
which I first referred. Here is one character, for example:

STARTCHAR CNS2-5071
ENCODING 17522
SWIDTH 985 0
DWIDTH 40 0
BBX 40 40 0 -3
BITMAP
0300018000
03e000c000
03c000e000
0380007000
038000700c
038000301e
0383ffffff
0388300180
039c1801e0
fffe0c01c0
03800e0380
0380070300
0780070618
0781830c3c
07c1fffffe
0fe1c0601e
0fb1c0781c
0fb9c0701c
1f9dc0701c
1b9dc0719c
1b8ddfffdc
3b81c0701c
3381c0701c
3381c0701c
6381c0701c
6381c7ff1c
c381c7071c
c381c7071c
8381c7071c
0381c7071c
0381c7071c
0381c7ff1c
0381c6061c
0381c0001c
0381c0001c
0381c0003c
0381c007fc
0381c00078
0381c00070
0301800060
ENDCHAR

The second number in 'BBX' (40) refers to the number of encoding lines to
follow.

Because that's so readable, it was a simple 10 minutes coding to turn 
0381c007fc into the Euphoria required {0,0,0,0,0,0,1,1, etc} and display the
character as a bitmap. Now I'll just write an indexing routine and all should be
well.

Thanks again for your help ...
