Hmm... I'm pretty sure some fonts have different x-height in the n and sc
shapes, and in those cases the accents may have to be different if they are
to be put at the same height above the x-height, provided all metric data
is correct. It is far from certain that fontinst automatically gets it
sufficiently right for this to be seen, though.

Thus I'd say no, but there might be a point in using some new macro instead
of \lc to form accent names.

Agreed. There are probably more cases like that.

The ETX and MTX files that come with fontinst are long overdue for a
complete revision. I've done some work on it (but progress is slow and I'd
really prefer that someone assumed maintainence responsibility for these
files) and it might in time (a loooong time from now, as it seems) become a
sort of v2.0 of these files.

As a first step I have tried to device some sort of draft standard for how
(La)TeX encodings are specified, which can be found at

  http://abel.math.umu.se/~lars/encodings/

An important novelty is that Unicode is taken as a standard in relation to
which encodings are defined. I had primarily intended it for discussion on
the LATEX-L list, but so far I haven't recieved any comments on it, so that
discussion never started. Feel free to send comments to this list instead!

In relation to item 2 above I might mention that in the t1draft.etx that
appears in that directory, there are a number of glyphs for which I there
use Adobe standard names rather than the names in the current t1.etx. All
the ETXs and MTXs should be changed accordingly, but it remains to see when
that will happen.
