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

function 'char'
	<main ctx instance>:1: in main chunk.
\fontchar #1->\ctxlua {fonts.char("#1")}

l.4 \fontchar{notequarter}

?

Please, help me.
