    Yes. Normalizing Unicode text on input is quite kosher, and generally
    a good idea.

    Well, on Mac OS X you can't guarantee that the decomposed things will
    display properly without font support, either (which means creating the
    precomposed glyphs anyway, and adding the 'morx' table to do the
    composition). Fortunately, Apple provides some *excellent*, free tools
    to handle just such cases…
