As alternative to embedding a font into a KF8 file, you could also install a custom font on the PW that will be available on all books as part of the regular font-selection screen. This includes old mobi and new mobi (KF8) files. All you need to do are these steps:
- connect PW to computer per USB - on usb-drive create an empty/new file with name: USE_ALT_FONTS
Hola, ¿El archivo vacío USE_ALT_FONTS dónde se pega, en el raíz directamente?
