The Unified Font Object (UFO) is a cross-platform, cross-application, human readable, future proof format for storing font data.

The UFO Design Philosophy

1. The data must be human readable and human editable.
2. The data should be application independent.
3. Data duplication should be avoided unless absolutely necessary.
