[Bug 1748495] The terminus font is no longer found by gvim, so text files come up with glyphs instead of characters.

--- Comment #30 from Hans Ulrich Niedermann  ---
I have found two ways to generate *.otb files for Terminus so far. Those are:

1. the fonttosfnt way which generates

* one TerminusBold.otb   from ter-u*b.bdf and
       * one TerminusNormal.otb from ter-u*n.bdf

with commands like

fonttosfnt -b -c -g 2 -m 2 -o TerminusBold.otb   ter-u*b.bdf
         fonttosfnt -b -c -g 2 -m 2 -o TerminusNormal.otb ter-u*n.bdf

2. the fontforge way which generates
       * one ter-*[bn].otb for every ter-*[bn].bdf

with a number of commands like

fontforge -lang=ff -c 'Open("ter-u12b.bdf"); Generate("ter-u12b.otb")'

At this time, I am inclined towards the fontforge way, as this uses the
stock fontforge shipped with Fedora, not from some COPR.

Now I am trying to read the current font guidelines, to fish out the
information applying for bitmap fonts from amongst instructions using
tools not shipped in Fedora at all (ttname), applying to vector fonts
only, etc.

I still want to maintain backward compatibility with older software
which still uses the old fonts through old rendering libraries. Not
everyone is using Pango and Gnome, after all.
