Metafont is a system for designing fonts, rather than a font format.
That is, like Postscript, it's a programming language.
The output format of Metafont is (or rather, ends up as) PK files, and
this is, if you like, TeX's 'native' font file format. This format _is_
documented, but the only documentation I'm aware of is within the source
of gftopk (see
<https://ctan.org/tex-archive/systems/knuth/dist/mfware>), and the
format does not, let us say, have extensive tooling support. It's a
fairly simple bitmap file format, but you'd be basically on your own if
If you have your desired character in a postscript font, then you can
potentially do the labour of setting up the mappings required to make
that accessible to non-PDF TeX. That's not well documented, because
approximately no-one does this any more. Fonts were always a nightmare
in original TeX.
pdftex is better at managing postscript fonts, but it can still be a
fuss, and you'd still have to work out how to get a postscript font with
the character you want (which may not be trivial)
Note that (if I'm understanding your goal correctly), you have a font
problem here rather than a unicode problem. You have presumably found a
font which contains the unicode character of interest, and your problem
is how to use that font within a TeX document.
Note also that if you're searching for information on PK files,
postscript fonts, and original TeX, and if for example you stumble
across advice in a 20-year old usenet post, don't dismiss it as antique:
that may be the most current online information about the problem.
The big deal with XeTeX and LuaTeX is that they support platform fonts,
such as TTF, OTF, and so on (unicode input is one of the other important
features of these programs, but quite separate). That means a lot of
font problems just evaporate. If you need to do interesting font
things, they are likely to be the right tools for the job.
The best place to ask for advice is on <https://tex.stackexchange.com>.
