Thanks NiLuJe! That's what I wanted to know. Now I'm curious to see what one of my books looks like on a KF! I'm generating the Mobi on Kindlegen/Kindle preview. Maybe it'll have my fonts!
When you say "these devices..." does that go for epub devices as well? I have only an old nook to check with and they show in it.
Goodness...I wish they'd quit playing games and settle on a format and actually make it work!
(I know...far from an original lament!
UPDATE: checked on kindlepreviewer and the KF one shows my fonts! YAYAYAY For those interested...I embedded the fonts in my epub file...and converted using kindle previewer. I think if you clean up your epub so that your fonts show in Adobe digital Editions, they'll probably work in KF.
Off to do a snoopy dance....(I'm so easily amused these days...)
