Embedding Fonts in Epub Files
The ability to embed fonts is a complex one and requires not only technical knowledge, but also legal knowledge and an understanding of device support.
Before you produce an epub file for a device which supports embedded fonts, you should first consider using one of the fonts already built into the device. See the list of fonts included with each device.
Epub2: (@font-face). The following font descriptors must be supported:
font-family font-style font-variant font-weight font-size src
For an example see: ePub Tutorial#Advanced formatting tasks
