Do you know what device each person is using to read with?

Different devices have different ways of doing things.

A Kindle needs to have the Publisher Font selected.
A Kobo just works.
Apple Books needs a file called com.apple.ibooks.display-options.xml in META-INF directory of the ePub containing the following text.

Code:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<display_options>
<platform name="*">
<option name="specified-fonts">true</option>
</platform>
</display_options>

For Apple Books, this is something you have to do before you send out the ePub. But you should just do it for everybody as it won't cause any issues for anyone not using Apple Books.

I'm mentioning this because the only way to do it is to send a note to each person telling them what needs to be done to get the ePub to display as you'd like with their device. There is no way to lock embedded fonts as you want.

Question, before you send your ePub to everyone, what is the embedded font you are using? The reason I ask is that a lot of embedded fonts do not look good on an eInk display (such as Kindle and Kobo) because they are too thin (need more weight).
