Combining Macron Right Half

It closes a Coptic overline that spans multiple letters.

Coptic is the Egyptian language of this writing tradition; an overline is a stroke above letters. On its own, ︥ does not mean “right” or mark an ordinary vowel.

Why was the Coptic half-macron encoded?

It encodes an older Coptic writing convention for digital text.

In Coptic writing, an overline could mark a shortened word: the letters shown stand in for omitted ones. It could also distinguish certain common words and names of gods or heroes; this second use is linked to Egyptian cartouches, outlines that enclose royal names.

Unicode represents the spanning stroke with an opening half, a middle join and this closing half. The digital pieces preserve an older writing practice rather than inventing it.

How do I type the final Coptic half-macron?

Put it after the span’s final Coptic letter.

For a two-letter span, write ⲓ︤ⲥ︥: the opening mark follows the first letter and the closing mark follows the second. For a longer span, place ︦ after each interior letter, as in ⲓ︤ⲏ︦ⲙ︥.

A combining mark needs a font that can position it on the full sequence. On its own, ︥ can look detached or incomplete because no Coptic span is present.
