- connect PW to computer per USB
- on usb-drive create an empty/new file with name: USE_ALT_FONTS
- create the folder: fonts
- copy your font in regular, bold, italic, and bold-italic into newly created fonts/ folder
- disconnect PW from USB
- restart PW ( menu->settings, then menu->restart )
The newly inshalled font will be visible (among a few others previously unavailable) in the font menu of a book. The only exception where it won't work is some KF8 books that have the font annoyingly hardcoded into the book (font won't change no matter which font is selected). The USE_ALT_FONTS will work no matter if the PW is jailbroke or not, but firmware 5.3.0 or 5.3.1 is necessary.
It works fine!!.
But I copied two fonts in the folder, and when I touch Aa, show me 20 fonts
It's strange, but very happy,
