    I'm working on the assumption that applications that claim to conform to
    Unicode actually do conform to it. If they don't, and it's not the font
    foundry's fault, then complain, complain, complain! It's not Unicode
    that's broken, it's the implementation.

    Nothing in the Unicode Standard says those oddball spaces have to work
    "correctly" with combining diacritics.
