I never realized I could have system font referenced for epub!

I did a quick experiment yesterday just out of curiosity.

I replaced an embedded font with system one by specifying its full path

for example : open style.css and replace "src: url(../Fonts/nameofembeddedfont.ttf)" with "src: url(C:/Windows/Fonts/nameofsystemfont.ttf) for the font family you want to use and it will do the trick.

bear in mind that you have to use forward slash as path separator, like web address.

this is useful when you use an app or device that doesn't have an option to choose the default font. and you can even set different fonts for different parts of the document(like TNR for header, Arial for body etc)

you can install just any 3rd party fonts to your system and use it if the device's offered fonts don't meet your requirement.

if anyone knows about which font is used for which part in a more graphical way, please let me know.

You might get it to work while using the Viewer, but it will fail on any other device.

Translation: This is a really bad idea.

The proper way to use default system fonts on anything (even old mobi supports 3) is to use a generic family name:
Serif
Sans-serif
monospace (like typewriter, telex, telegram or terminal/console)
cursive (fake handwriting)
fantasy

Ancient kindles only have:
Serif
Sans-serif
monospace


Each ought to also support Normal, Bold, Italic, Bold+Italic.

CSS
font-family:serif;

Oblique, italic and cursive are different:
oblique is making a font slant if there is no italic, but oblique families exist.
Italic fonts don't exactly match the Normal version and are not just merely slanted as in oblique. Called Italic because they were invented or popularised in Italy in typeset books.
Cursive fonts might not be slanted like oblique or italic, though they might be. They give a closer to joined up script style. Clue in name.

my bad! I thought I found the final solution but come to think of it, I was wrong.

But I read books on PC 99% of the time, and for 1% I can just read them in default(ugly) font at worst. not very harmful I think.
