This happens when my client opens her FXL e-book in iBooks on her macOS machine.
The e-book is created in Sigil on the Windows 10 platform.
Is it:
- A conversion issue between Mac and Win?
- A broken font file on the client's computer?
- An issue with character encoding? (Currently UTF-8)
- A bug in iBooks?
Any suggestion to solving this issue is appreciated.
