Hello David,

Thanks for your explanations.

Is this a problem of how the fonts are encoded, or that the glyphs
are not freely available. If it's the later, then that doesn't have
anything to do with the plane 1 vs. pua issue. If the former, it
should not be too difficult to take a font and recode it, if
it is a free font.

Just in case this is not already listed as a last call comment,
I think it would be very important to fix this before publishing
the second edition. If you have problems with getting appropriate
glyph images, I suggest you talk to somebody from the Unicode
