I was charging my Paperwhite 1 yesterday and switched off the screen after I disconnected it from my computer. The screen showed that it is updating the font and asked me to wait. I found it strange and switch on the screen. Nothing happened. I checked and I didn't have the Wi-Fi on. To be on the safe side, I switched on the Wi-Fi and see if there was any update available. Nothing. Maybe I broke the procedure of an update? Is there any update of fonts recently?
My Paperwhite works and I don't see any difference in the fonts.
