Description of the new feature / enhancement

Hello, Greek Polytonic characters are specially difficult to work with, (even if using the Greek Polytonic keyboard), most of the accents are not included in any of the character sets, so most times I have to find them through unicode

It should include these: ά, ὰ, ᾶ, ἀ, ἁ, ἂ, ἃ, ἆ, ἇ, ᾴ, ᾲ, ᾷ, ἀ, ᾁ... (and so on for ε, η, ι, ο, υ, ω)

Scenario when this would be used?

When writing ancient greek, usually by philosophy writers and researchers
