Hi! I'm back again with my question. I really want to get Unicode 'Quarter Note' symbol, either from standard or custom font. The following example does not work, while the font (Symbola) is found. I probably did not define something, but I don't know what. \starttext \startfont[file:Symbola602 sa 2] \fontchar{notequarter} \fontchar{musicalnote} \fontchar{musicalnotedbl} \fontchar{sixteenthnotedbl} \stopfont \stoptext ! LuaTeX error ...tminimal/texmf-context/tex/context/base/cldf-com.lua:58: attempt to call global 'format' (a nil value) stack traceback: ...tminimal/texmf-context/tex/context/base/cldf-com.lua:58: in function 'char' ...tminimal/texmf-context/tex/context/base/font-ctx.lua:830: in function 'char' <main ctx instance>:1: in main chunk. \fontchar #1->\ctxlua {fonts.char("#1")} l.4 \fontchar{notequarter} ? Please, help me. Regards, Vyatcheslav
