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.

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 Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Ah, interesting!

\definefontfeature[liga][liga=yes] \starttext fi {\feature[-][liga]fi \feature[+][liga]fi} \stoptext
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!
