UTF-8 is a variable length encoding. Characters on the US keyboard can be
represented by 1 byte. Maximum two bytes are needed for most European
characters, Greek, Cyrillic, Hebrew and Arabic. Three bytes can represent
virtually every locale, but in some rare cases up to four bytes are
required to represent a single Unicode symbol.
I believe it is up to 6.
In theory, UTF-8 could represent up to 31 bits of payload using 6 octets.
However, the Unicode standard was amended and now says that only up to four
octets are valid. Looking at the manpage here, it still explains the
encoding using up to six octets.
One thing which concerns me, and I haven't found out about yet, is whether
the musical symbols have any specifiction about size, origin, and spacing.
I can write "Sonata in Eb" (with a proper flat sign) in a number of
microsoft-supplied fonts. But often the flat is the wrong size and comes
with much too much space around it for this usage.
I believe Unicode doesn't make any such specifications, so it is up to the
font designer to 'fix' this.
