Dear Hans (or anyone else),
There are some fonts (including Lucida) that don't have all the needed
character. A font feature "compose=yes" has been added to MKIV, but
that one doesn't work for Lucida or any other Type1 font.
My current fallback is to use:
% this doesn't help
% \definefontfeature
% [compose]
% [liga=yes,kern=yes,tlig=yes,compose=yes]
\beginNEWTEX
\catcode`č=\active
\catcode`Č=\active
\defč{\buildtextaccent\textcaron c}
\defČ{\buildtextaccent\textcaron C}
\endNEWTEX
But nevertheless a few questions:
- Is there some "accessible" method to compose a few characters in the
font (not too low-level) as opposed to using active characters? The
code must be there already since this is supposed to work for OpenType
fonts.
- Is there any way to fix horizontal and vertical position of accents
(on glyph-per-glyph basis; that one probably needs to be slightly more
low-level; maybe using lfg files)?
- Do lfg files work for non-opentype (Type1) fonts?
Thanks a lot,
Mojca

ok, positioning could be improved I guess but so far no one bothered
about this feature

Oh, I have tried that; actually I did
\definefontfeature[default][liga=yes,kern=yes,tlig=yes,compose=yes]
as well as \addff{compose}, but it had zero effect since I used that
*after* \setupbodyfont instead of using it before. This was a bit
weird since features for OpenType fonts can be switched on and off at
any given time and I didn't realize that order was important.

(I started fixing vf fonts of Lucida for pdfTeX, but I'm not sure how
to proceed; and now it may not be needed any more.)
There are two problems. Even \buildtextaccent creates an ugly č and
that dates back to Knuth's TeX (TeX assumes that every letter is
symetric which holds for just about any letter but c). But I agree
that this is highly esoteric request.
However compose=yes creates an unacceptable uppercase Č, at least in
Lucida, much worse than what TeX does (and already TeX does it badly).

\addff only works for opentype (unless I make a pseudo feature which is
a lot of work for something that is never dynamic)

I've sent you a test file. A problem is that the boundingbox of an
accent is rather unpredictable and I might need to write a more clever
function for it. So we need more tests with different fonts ... (we can
best do that off-list).
