	It happens that the native languages of the most people of the
	world either use extensions to the Latin script (beyond those in
	ASCII, such as J or W), or use a script not derived from Latin
	at all.  (Greek-based scripts are not uncommon, for instance;
	FWIW, the Latin script is based on the Greek one itself.)

	Good luck selling your product to anyone speaking French, Greek,
	Polish or Russian.
