Another less known feature, that just shows that there's a need to document
now the case of the isolated combining marks without an appropriate letter,
denoted by some other symbols.
These symbols are currently not listed exhaustively, and this does not help
making the notations easily interoperable, as many font designers will
forget to implement them, by ignorance of the expected needs and lack of
interaction between those designers that have implemented something.
