Made 0F00, 0F02 and 0F03 be "symbols" rather than "combinations".

They should not be decomposed on transliteration.

    Made 0F0E (//) a "symbol" rather than "combination".

    Made the Sanskrit aspirates and k+Sh into foreign consonants,
    rather than "combination"s.  This doesn't actually affect the
    current code, but better reflects what it is doing (after the
    change to canonicalize these as single "precomposed" characters).

    Made the "strongly disrecommended" vowel signs "deprecated" rather
    than "combination".
