U+1FBD GREEK KORONIS: ᾽

[IS META]

Dear subscribers to the Unicode public general mail list,
Can anyone tell me what the intended use(s) of the character ᾽ (U+1FBD
GREEK KORONIS) is/are, please? Or, failing that, where I can find out?

Many thanks in advance for any help you can provide. Apologies if this is
not the right forum in which to ask this question.

Yours faithfully,
I.S.M.E.T.A.
