  <para>
   Retrieves the name of a Unicode character.
  </para>
  <para>
   Depending on <parameter>type</parameter>, the resulting character name is the "modern" name or the name that
   was defined in Unicode version 1.0. The name contains only "invariant" characters like A-Z, 0-9, space, and '-'.
   Unicode 1.0 names are only retrieved if they are different from the modern names and if ICU contains the data for them.
