I am trying to set text in the Syriac font Estrangelo Edessa. Right now, I have the following (taken for the wiki): \definefontfeature[semitic-complete] [mode=node,analyze=yes,language=dflt,ccmp=yes, autoscript=position,autolanguage=position, init=yes,medi=yes,fina=yes,isol=yes, mark=yes,mkmk=yes,kern=yes,curs=yes, liga=yes,dlig=yes,rlig=yes,clig=yes,calt=yes] \definefontfeature[arabic] [semitic-complete] [script=arab] \definefontfeature[syriac] [arabic] [fin2=yes, fin3=yes, med2=yes] \definefallbackfamily[mainface][rm][estrangeloedessa] [range={syriac}, features=syriac] \definefontfamily[mainface][rm][STIX Two Text] [protrusion=quality, expansion=quality, mode=node, force=yes, features={default, f:oldstyle}] \setupbodyfont[mainface, 20pt] \starttext Hello world! { \setupalign[r2l] ܐܝܟ ܟܝܢܐ ܕܐܐܪܣ ܡܲܥܕܢܘܬܗܘܢ ܘܡܲܥܒܿܕܝܢ ܩܪܒ̈ܐ ܘܚܣܡܐ ܠܗܠܝܢ } \stoptext Though the file compiles, the Syriac text does not look the same as the source text (Estrangelo Edessa unicode). See attachment. Any guidance in fixing this will be gladly received. Alan Disclaimer: I do not know Syriac.
