Pango marshals a collection of fonts that will handle all the unicode
chars in a string. cairo is used to draw pieces of the string with the
font that provides the unicode glyphs.
In general no font has all the unicode glyphs so to draw a arbitrary
unicode string you must either have a library like pango or implement
it yourself.
