Hi,
with LuaLaTeX I used to use the selnolig package to disable
inappropriate ligatures. With ConTeXt I have just inputted the list
prepared by Hraban (based on a wordlist originating from selnolig),
but then ran into a curious bug (?) with disappearing characters (see
my posts from a couple of days ago). I'm now converting this list to
the \blockligatures mechanism (instead of using \replaceword), which
also has better kerning support due to Hans. When done, I'll of
course share this on the Wiki if there's any need for this.
Now I'm wondering how others deal with inappropriate ligatures. Do
you just ignore them? Do there just so many.
What do you think?
I played a bit with what we have and in a next upload you can do this:
\startexceptions[de]
au{f-}{f}{ff}(f\zwnj f)asseyou block them on an ad-hoc basis, like
whenever they occur? Do you use scripts to pre-process your files
before typesetting? Do you just disable ligatures globally?
I tend to think there must be an automatic way to deal with the most
awkward cases. The problem is that
\stopexceptions
\showglyphs
\starttext
auffasse
then is like:
au\discretionary{f-}{-f}{f\zwnj f}asse
\stoptext
Oh, that looks interesting. So that would essentially be implemented
like hyphenation exceptions? Any drawbacks? Performance hit with large
exception lists? Kerning?
in a next release a
\zwj block ligature, permit kern
\zwnj block ligature, also inhibit kern
for now, lmtx only
Hans
