3e. Catalog of Support Characters in Unicode

Apart from the repertoire of characters used in typesetting neumatic notations, there are three "support" characters which may be used as purely functional indicators.

Formation of complex neumes: a + b = ab, where "a" is the base neume and "b" is a simple attaching modifier.
However, when a compound formation is too complex or problematic (where there is a possibility of failure to display correctly in some applications), then we have eliminated the risk of display problems by having: a + b = c, where "c" is a stable pre-composed substitution.
Provide examples.
