    I think you might be overstating the case. Suppose that the English-speaking
    world had to make do without the letter 'k' in domain names, and people had
    to type SNN.com instead of CNN.com, etc. There would clearly be substantial
    interest in correcting that situation. So IDN, correctly, also allows
    Latin-script-using languages to flesh out their support.

    But if 'k' really were not used in any real publications in a modern
    language, then it would be a different story (see my previous message).
