Some ligatures don't work in latest LMTX

Some ligatures don't work in latest LMTX

[-- Attachment #1.1: Type: text/plain, Size: 713 bytes --]

Hi everyone. The following example works fine with MkIV, but fails
with latest LMTX.

To be specific, the lam-alif ligature isn't working. Compile with both
to see differences.

Majalla is a Windows font, so I guess it's available for testing:


\mainlanguage[arabic]\definefontfeature
  [arabic]
  [mode=node,language=dflt,script=arab,
   init=yes,medi=yes,fina=yes,isol=yes,
   liga=yes,dlig=yes,rlig=yes,clig=yes,
   mark=yes,mkmk=yes,kern=yes,curs=yes]\definefontfamily[main][serif][sakkalmajalla][features=arabic]\setupbodyfont[main]\setupdirections[bidi=global]\starttext
أهلاً وسهلاً\stoptext

Is that a bug or are more features to be specified? Thank you in advance.

Jairo

Thank you very much, Hans. Ligatures now work. However, diacritics aren't
properly placed even using "features=arabic" (they appear below letters in
LMTX). ConTeXt MkIV still gives correct output.

Thank you in advance.

Hmm, it works for Persian because this uses less diacritics than Arabic.
The following fails with LMTX:

\definefontfamily[main][serif][notonaskharabic][features=arabic]

\setupdirections[bidi=global,method=one]

\setupbodyfont[main]

\starttext

\obeylines

Hi, Hans. Could you please check this out? It works for MKIV, but in LMTX
vowels are misplaced. Thank you in advance.

It works here but i have different code in the meantime. We're in a 
transition to an lmtx version of the font handler. In lmtx we need to do 
a bit more checking when we are in in compact font mode so it might be 
that there is temporary loss of some functionality. In principle mkiv 
and lmtx should do the same as there is no real change in logic.)

I'll push an update later today,

Hans
