Hi Hans,

I have already installed some Chinese TTC fonts, e.g. NotoSerifCJK-Regular.ttc. But when I use mtxrun command to search them, I get an error.

$ mtxrun --script font --list --file NotoSerifCJK-Regular.ttc
lua error : function call: ...e/garfileo/opt/context/tex/texmf-linux-64/bin/mtxrun.lua:10012: bad argument #9 to 'format' (number expected, got string)
