That's fine for new fonts, but it's not much help when using existing
fonts. Lilypond's Feta and those from Coda and Sibelius usually have a
different range of glyphs from the Unicode set, so they can't be
directly remapped. For example they may have a combining flag symbol
(a single flag that can be drawn as many times as required onto a note
stem) instead of separate glyphs for 1, 2, 3, 4 or 5 -flag notes as in
Unicode, and they often include single glyphs for things like mordents
that are composite in the Unicode set.
A practical problem for people using Qt is that you can't address the
musical symbols range at all using Qt's character class, which only
supports UCS-2 (16 bits without surrogate pair support). There's no
way around that except to use something other than Qt for rendering.
(That's one reason Rosegarden uses Xft directly... that and a few other
dumb things Qt does that make it really hard to use any font that
doesn't have a full complement of latin1 symbols.)
