+<p>A font face is an object that represents a single face from within a
+font family.</p>
+<p>More precisely, a font face represents a single face in a binary font file.
+Font faces are typically built from a binary blob and a face index.
+Font faces are used to create fonts.</p>
+<p>A font face can be created from a binary blob using <a class="link" href="harfbuzz-hb-face.html#hb-face-create" title="hb_face_create ()"><code class="function">hb_face_create()</code></a>.
+The face index is used to select a face from a binary blob that contains
+multiple faces. For example, a binary blob that contains both a regular
+and a bold face can be used to create two font faces, one for each face
+index.</p>
