The names do NOT always provide correct descriptions of the
characters.  This is especially true for "digraph" and "ligature"
(and in the case of U+00E6 too), as well as (e.g.) SCRIPT CAPITAL P,
which is neither script, nor capital (it's lowercase), though
it is a p...  In addition, there are different flavours of ligatures.
E.g., it is quite legitimate to render, e.g. LIGATURE FI as an f followed
by an i, no ligation, whereas that is not allowed for the ae
ligature/letter, nor for the oe ligature.
