The text of my message to KDP Support:
==========================
Subject: Embedded Fonts are Stripped on my Kindle Fire 5G
The KDP-generated MOBI for my draft eBook:
1. Renders fine in the MacOS Kindle Previewer & Kindle App;
2. Fonts are substituted in Kindle App on iOS but the result is acceptable.
3. Fonts are stripped & user selectable on my Kindle Fire 5G – unacceptable.
I use special fonts to convey source information and the book won't work without them. What steps must I take to make my fonts render the same on a Kindle Fire device as they render in the Kindle Previewer for the same device?
==========================
NOTE: The latest
KindleGen guidance indicates that since I'm using the latest
Kindle Previewer for conversion, I'm also getting the benefit of KF8 formatting.
