I know people hate to hear this phrase, but This Is Not Unicode's
Problem. Unicode assumes that sufficient rendering-engine power is
available to display whatever the application (OS, user app, whatever)
claims to be able to display. The canonical equivalence does matter.
The existence in a 12-year-old font of some character mappings but not
others does not change this.
