Yes, Brian, thanks for the link. One reading of
http://www.tldp.org/HOWTO/Unicode-HOWTO-5.html
suggests that paps may be doing it the only way possible,
apart from the duplication of each occurrence of a glyph.
I've just installed uniprint and I can't see that it does
anything different, except produce a much larger file.

$ paps --font="Freemono 10" --left-margin=54 --top-margin=54 --paper letter \
 UNICODE-chars.txt > unicode-chars.ps
$ uniprint -out unicode-chars-uniprint.ps -in UNICODE-chars.txt \
 -font /usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf
uniprint: printed 17 pages.

$ ps2pdf unicode-chars.ps unicode-chars.pdf
$ ps2pdf unicode-chars-uniprint.ps unicode-chars-uniprint.pdf

    45395 UNICODE-chars.txt
  7344022 unicode-chars.ps
  3457331 unicode-chars.pdf
 27775050 unicode-chars-uniprint.ps
  7993797 unicode-chars-uniprint.pdf

The comparison is as fair as I can make it: paps opens three
font files AFAICT: FreeMono.otf, DejaVuSansMono.ttf and
DejaVuSansMono-Bold.ttf, so I gave uniprint the second one.

I gave up using a2ps at least a decade ago because it can't handle
Unicode; AFAIK there's no sign of its adopting it at all.
I'm always on the lookout for a "pa→pdf" successor to pa→ps, but
see no sign of it on the horizon.

Cheers,
David.
