0m Removed 19 null character(s) from fontname --> MicrosoftYaHei-Bold

Hi guys:

I just moved from latexmk to tectonic. I really like the tectonic.

When I tried to compile my file which has some msyh.ttc font in it, I got couple lines saying : [0m Removed 19 null character(s) from fontname --> MicrosoftYaHei-Bold.

I’m lost with this. Can someone explain this to me?

Best Regards

As far as I can tell, this message has to do with the font name that is stored inside a font file. Apparently some font files store names that include NUL bytes, possibly due to to UTF-16 encoding. As far as I can tell, this message is just telling you about one of the font files that you’re using, you can safely ignore it.
