Hi all,
I know I can break ligatures with \/, like Auf\/lage, but is there a general dictionary approach, like \hyphenation{} ?

That's a nice idea. If something like that existed, it could be used to change 's' to 'ſ' in relevant places, too.

There are > cases where the brace group disappear when pdftex tries out > hyphenation points. in traditional tex hyphenation is integrated in the par builder which comes after ligaturing and kerning and tex only hyphenated where it 'makes sense' and in the process (multi-pass, going into disc nodes) it will consult (deconstruct / reconstruct) ligatures and at that point it's not known that the input had a {}. Tricks like inserting something in between is also unreliable when done at the wrong time and it can also prevent for instance kerns of hyphenation.

Oh, yes. Thanks for the analysis. I get the startligature-f also on hyphenation, like in auf-fällig, so that the arc of the first f (that is supposed to touch the second) reaches over the hyphen.

It also responds to tlig or liga features, even if they’re implemented as single (i.e. not ligature) glyphs (there are e.g. different f glyphs). Maybe it’s set up in a strange way, but I don’t think it’s that bad. Of course I don’t have your level of insight. My problem with Alegreya’s *design* it just that it’s not very well suited for digital printing, it needs a high resolution to look good.

It defines the kerning between f and i. I also added "f" and "b". And after playing with the values and setting up exceptions I understand now why Hans hates the Alegreya font(s): While the kerning works, the font still uses the long-arced f (that is meant for creating ligatures). I still like the design, but will consider different fonts for upcoming books.

Hi all,
just two quick questions: a couple of weeks ago, there was a long
discussion on ligature exceptions in, e.g., German. Hans provided an
elegant new mechanism (\startlanguageoptions). So my two questions:
1. Is the old mechanism (\replaceword[eg][Auflage][Au{fl}age]) now
obsolete? I tried using it, but unwanted ligatures still occurred. If it
is indeed deprecated, I'll add a note to the wiki (this would mean that
the current texlive version does not have the new mechanism and the
latest lmtx doesn't use the old one, so that's somewhat problematic).
2. Both mechanisms only work for complete words, is that right? So I
can't just provide a pattern such as "uf|forder," I have to provide a
full list with all inflected forms:
auf|fordern
auf|fordert
auf|fordernd
Auf|forderung
Auf|forderungen
and for 1-3 also the forms with a capital letter.
Thank you!
Thomas
