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.

|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.
(you can probably best use the already define arabic featre because it
also does some contextual stuff)
anyway, there was an issue with the state querying (isol etc) as side
effect of another thing .. fixed in next upload (there haven't been
fundamental changes to the font handling for quite a while)
