Iirc, there were already some attempts to support it.
Did you search the archieves?

Why LilyPond 2.14.? It's _very_ old and very outdated.
For another thing up to now only guile-1.8 is supported.
I've an experimental branch where guile-2.2 is used and LilyPond is
more or less working. Look at the difference (all done in a native
guile-prompt, no LilyPond):
guile> (version)
"1.8.8"
guile> (define strg "’s He")
guile> (map string (string->list strg))
("�" "\x80" "�" "s" " " "H" "e")
guile>
As opposed to:
scheme@(guile-user)> (version)
$4 = "2.2.2.5-96c9"
scheme@(guile-user)> (define strg "’s He")
scheme@(guile-user)> (map string (string->list strg))
$5 = ("’" "s" " " "H" "e")
Cheers,
