    Ah, Rick, you really shouldn't set up lines like that...

    U+1D047 BYZANTINE MUSICAL SYMBOL OLIGON NEO
    U+002D HYPHEN-MINUS

    Not to mention the pitch letters U+1D0E9 - U+1D0EF, which are just
    stylised Greek letters (and won't be particularly distinguishable from
    Greek or Latin at plausible font sizes).

    (I fail to see a good reason for not banning them; URLs are understood
    to be text, and neumes are no more textual than Gregorian neumes. But
    this issue will not be decided by the UTC, in any case...)

  Many among their proselytes had sold their lands and houses to increase
   the public riches of the sect --- at the expense, indeed, of their
   unfortunate children, who found themselves beggars because their
   parents had been saints. (Edward Gibbon, _Decline and Fall_.)
