<character> An image used in the visual representation of
characters; roughly speaking, how a character looks. A
font is a set of glyphs.
In the simple case, for a given font (typeface and size),
each character corresponds to a single glyph but this is not
always the case, especially in a language with a large
alphabet where one character may correspond to several glyphs
or several characters to one glyph (a character encoding).
Usually used in reference to outline fonts, in particular
TrueType.
