I'm about to push a book through KDP, and noticed a weird problem. In my book, every single glyph is replaced with a rectangular box in the default font size, as though the font is missing literally every character, and all font sizes are being ignored.

With an earlier Kindle Previewer app on my Mac, I had problems with Kindle's Paperwhite mode (removed in the current version) doing that, but only when a built-in font was selected—it worked correctly in "Publisher Defaults" mode—so I assumed it was simply a font problem on that machine. Now that I'm seeing the same behavior in the online KDP previewer (and on a much wider range of devices), I'm a little more concerned.

Given that text is text, and can't possibly be anything but text, and given that it obviously is failing with Amazon's fonts, rather than with my own, I'm inclined to assume that Kindle Previewer (including the version they use on their website) has simply become broken beyond all repair, but I was wondering if other folks have noticed this problem with their KF8 books.
