    This is most easily and most naturally controlled by the end users of
    such introspective setups - simply do not allow conflicting PUA code
    points on their systems. In such a scenario, the operating system is not
    forced to make decisions.

    But if there were multiple PUA fonts with competing code points on a
    single system, I suggest that OS'es should simply go with the first font
    (defining "first" as that font whose file name has the lowest Unicode-
    code-point-based "alphabetic" order).
