Calibre is not reading an embedded font
Can anyone advise why Calibre is not reading the embedded font in the attached book?

The fonts have issues (damaged?).

There are marks in the book file browser and debug (lists the items issues)

TeX Gyre Bonum is part of TeX. Did you download the original font from CTAN?

No, just sent the ebook as it was originally - thanks for the link however. I suppose I can use Calibre to replace the embedded font with the otf files from the page.

I used Sigil to remove the font obfuscation and extracted them from the ePub. When I attempted to open the 3 font files with FontForge, etc., the files were stated not to be valid font files. I also noticed that the files were a lot smaller than I would expect from a font file with a reasonable number of glyphs.

I downloaded the regular, italic and bold variants and replaced the existing font files with the downloaded one and the embedding seems to work happily enough now except for the weirdness of having the oblique entry when oblique is not used and the S-EB id which is used in every file.

Maybe in the originally posted EPUB some font subsetting was applied and that software was misbehaving. Or the originally used font was crappy in the first place.
