I saw the GitHub pull request.
Let me see if I understand...
The standard fonts provided with the Kindle do not have the characters 0xFE01 to 0xFE16?
If the user adds a custom font that contains the characters 0xFE01 to 0xFE16, the :;, and 。. problems go away.?
I think what I'll do is
- Put in your changes for handling the single quote '.
- Put in your changes for the Kindle vertical text.
- Add a note to the 1st post in this thread and the GitHub page to recommend Kindle users add a custom vertical font that contains all of the vertical characters to their and point to your GitHub repository.
- Change the dialog text from "Optimize presentation for Kindle reader" to "Optimize presentation for Kindle reader with original fonts"
