Not necessarily. Some fonts have the "ascii tilde" equal to the tilde
accent (or at least in the same vertical position) whereas other fonts have
the ascii tilde vertically centered

Perhaps. But if you use OT1 (TT variant or not) then you loose all the
Central European glyphs in the font, as those are not present in the OT1
encoding. You should most likely use T1 instead, as very few languages
except English can be fully accomodated by the OT1 encoding.

There should be one, but it is missing in some fontinst versions. It is
included in v1.910+, but that version won't work with fontinst v1.8. OTOH
ot1.etx is written so that it automatically switches to typewriter
behaviour whenever the monowidth integer is set, which it usually will be
when you are installing a monowidth font. (Not that I think that is very
well explained anywhere, but it is the case.)

I cannot see that using ot1tt.etx would solve your problem, though, as it
too would use the name tilde for the tilde glyph it puts in the font.
Instead I would say the short piece of MTX code you sent yesterday is the
proper solution to your problem.
