Any decent Unicode Font _should_ have musical symbols.

Hmm - hard to debug. Just a shot into the dark: what's your locale? (type 
'locale at 
the shell prompt) Mine is:

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"

As you can see, I've configured my locale to use utf-8. If your locale isn't 
utf-aware
Cairo will render the musical characters as two bytes.
