I think Rick is correct. The clear choice here are the
corner brackets: U+2308..U+230B, LEFT CEILING, LEFT FLOOR, etc.
Note that *many* of the musical symbols, when used in musical
layout on staffs, are simply "placeholders" for the symbol,
used in complex drawing operations that may morph them in
many ways when actually rendered.
If you look at the example provided by Simon Montagu, it seems
clear to me that the corner brackets are appropriate placeholder
symbols in this case. And they are no more unsatisfactory than
the use of ASCII 1, 2, 3, 4, 5 to indicate fingering symbols.
