    OK, Doug, I accept that a "may" is a "may" and an implementation in
    which the tilde on an i collides with neighbouring characters is Unicode
    compliant. It's just bad typography (unless some special effect is
    intended). Any typographers on the list care to disagree? I would
    suggest that it is also bad typography for a space, diacritic
    combination to be wider than the diacritic, as long as the typographer
    realises that space is being used here as a convention and, according to
    the standard, does not have the usual properties of a space.
