Thanks.  Meanwhile, we got an answer – an example of a real-world
score containing the two characters in question was given.  The
conclusion is that those accidentals, while not seen today normally,
were really used for music notation before being added to Unicode.
Whether they were actually used within plain text (which is, more or
less, the aim of Unicode) is another issue but no longer of relevance
today.
