Since I'm not an Apple developer, I'm not really sure where to look for
such information. From what I've found through Google, it seems that the
relevant library is simply CoreText, but I may completely misunderstand how
OS X libraries work...

I've tried, but haven't been successful... m17n-db can be installed, though
it requires downloading the charmaps and installing GNU/gettext because the
program msgfmt isn't part of OS X. (It's part of GNU/gettext but not of the
gettext that comes with OS X, it seems.)

Then, however, configuring m17n-lib failed with the following message:

autoreconf: running: aclocal --force -I m4
autoreconf: configure.ac: tracing
autoreconf: configure.ac: not using Libtool
autoreconf: running: /usr/local/Cellar/autoconf/2.68/bin/autoconf --force
configure.ac:52: error: possibly undefined macro: AC_PROG_LIBTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: /usr/local/Cellar/autoconf/2.68/bin/autoconf failed with exit
