Strange behavior with embedded fonts
I've embedded a font (UniFrakturCook) in two ebooks with Jutoh.
Everything is fine, exept on the Kobo. Some letters, the large S and the small g are looking very strange or are invisible.
Several people have tested these books. No problem on other devices, but always on Kobos. Similar problems were reported for other embedded fonts. With the same letters S and g! And some others.
The font works well with other readers and with other software.
Must be a really strange bug in the Kobo firmware.
The books are from Klabund. "Romane der Leidenschaft" and "Kleine Literaturgeschichte in einer Stunde". Both uploaded in Mobileread.
