I've just got a Nook ST and want to read Japanese books on it.
I've seen some guides about converting ebooks by setting Droid fonts using "Use Device’s System Font" in Calibre. However, I can't find this setting and looking at this thread
https://www.mobileread.com/forums/sho...d.php?t=203568 this seems outdated.
Does anyone know whether the device's system font is used, and how to make ebooks UTF-8?
