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)

Best regards,
