Hi, the following example compiles fine with LuaTeX, but LuajitTeX fails to find the font. \setupalign[r2l] \definefont[Sheherazade][name:scheherazade*arabic at 18pt] \starttext \Sheherazade أهلا بالعالم! \stoptext fonts > defining > font with asked name 'scheherazade' is not found using lookup 'name' fonts > defining > unknown font 'scheherazade', loading aborted fonts > defining > unable to define 'scheherazade' as 'Sheherazade--0' The font is in the font database and regular LuaTeX succeeds. mtxrun --script fonts --list -all scheh scheherazade scheherazade /home/marco/.fonts/scheherazade/ScheherazadeRegOT.ttf scheherazadenormal scheherazade /home/marco/.fonts/scheherazade/ScheherazadeRegOT.ttf This might be related to the thread from a few days ago: http://thread.gmane.org/gmane.comp.tex.context/83871/focus=83877 Marco PS: The font can be found here: http://scripts.sil.org/cms/scripts/render_download.php?format=file&media_id=Scheherazade-2.000&filename=Scheherazade-2.000.zip
