A fundamental problem, among many, of Unicode is that, most people can't recognize most of local characters. With the internationalized context of IETF, it is prohibitively impolite to spell names of people in a way not recognizable by others. Thus, for the internationalization, names of people MUST be spelled with characters recognized by all the international participants, which means ASCII is the only choice.
