This is Calibre 8.12 on MacOS 15.7.1 I've only recently upgraded to Calibre because of the platform restrictions.

Unfortunately, there is a problem with the reader so that all glyphs are rendered as errors. This is not a Calibre version issue as I've just checked on another machine with 7.26 and the problems are the same.

I'm enclosing a screenshot demonstrating the issue: I can't even choose a different font!
