Compare the first page of the table of contents with the result produced by another viewer; they are not the same.

I'm looking at page 2, and most viewers have similar rendering to mupdf:

Firefox PDF.js: Same as MuPDF.
Acrobat Reader 9: Has tofu in places, otherwise same as MuPDF.
Ghostscript: Has tofu in places, otherwise same as MuPDF.
Evince: Looks completely different.

Since PDF.js, acrobat, and ghostscript all look the same as mupdf, I'm going to assume that Evince has the correct appearance?

I am seeing rather a lot of FreeType error messages for the Identity-H embedded NotoSansHans-Regular font, which leads me to suspect an issue with FreeType and/or the font file is causing these differences.

The given customer number is for a customer that doesn't use MuPDF, so it seems likely it's been added in error.
