The same could be argued for U+0301 yet this already serves as the acute
accent when used with Latin script, positioned above capital letters, and as
the tonos or oxia accent when used with Greek script, positioned to the left
of capital letters. Similarly U+0300 serves both as the Latin acute accent
and the Greek varia accent. These combining marks also behave differently
when used for Vietnamese. Script/Language dependent behaviour of combining
accents is already a feature of Unicode, so U+0313 should be able to
function as both the Greek spiritus lenis and as a diacritic for composing
the Egyptological Yod when used with Latin script.
