Dear Knights,
What is the canonical way to break a ligature in MkIV? The canonical TeX
way, e.g.
f{}i
does not work if the feature liga=yes.
The zero-width joiner or non-joiner will do it but that seems ad hoc or
abusive ;-) since those are really for cursive scripts like Arabic and
Syriac.
Best wishes
Idris

that's more a side effect of the old engine where lig building happened
interwoven with the parser (optimization) while in luatex this is nicely
separated (cleaner) you can put a kern in between but then of course you
wont get kerning with the other chars

quite a claim ... afaik devanagari also needs them
anyhow, just don't enable ligatures if in doubt (some fonts have
language dependent ligatures) ... it's somewhat arbitrary to have only
'f' related ligs anyway

This is just for having a control to make sure the test file I'm preparing
for a \feature wiki entry is actually working right, so naturally I can't
use \feature for the control :-)
But that is a nifty example, Wolfgang, so I may include that one on the
wiki too!
Thanks Hans, Wolfgang, and
Best wishes
Idris
