Re: [NTG-context] LMTX error processing Adobe Arabic Naskh font
Problems I and II are apparently solved in the latest update. As for III, the following works: \definefont[ARABICFONT][file:almfixed.otf*arabic at 28pt] \noheaderandfooterlines \setupwhitespace[big] % \starttext \startTEXpage[offset=1ex] % \setupdirections[bidi=global,method=one] \righttoleft % \setupalign[r2l] % \dontleavehmode \setupalign[r2l] \ARABICFONT \utfchar{"062E}\utfchar{"064E}\utfchar{"200D} \stopTEXpage % \stoptext As Hans explained off-list, TEXpage interacts with hmode and vmode in ways that may appear unpredictable in some circumstances. In this case the circumstance is % \setupdirections[bidi=global,method=one] Uncommenting this line will bring the bidi issue back, but it's not needed for the desired result.
