Now you made me think. In general, with C, zsh, Elisp,
etc., I always want neat short files to reflect themes
and areas of activity, if not straight modules, which
also go into separate files, of course. However, for
LaTeX, without thinking of it, I've had several
projects as singular, very long documents and the only
thing I kept outside was the file with the Biblatex
sources, containing only what didn't relate in
particular to my work (i.e., the pages of references I
had in the .tex file). So let's see... - no, I think I
prefer the Unicode figures in separate files, after
all.

Most definitely, I usually use tr for that kind of
stuff but I don't know if it can be used straight off
in this case. But there should be several tools that
can be put to do that without too much fuss. aa2u even,
perhaps?

I also send this reply to gnu.emacs.help because there
is the enigmatic lisper who wrote aa2u, and he will the
best person to ask, of course. So hailing frequencies
should be open. (Next time we will explore the secrets
of time travel. Or will that be - the previous time?)
