Basics

Create an AtticOrthography:

using AtticGreek, Orthography
attic = atticGreek()
typeof(attic)

AtticOrthography

It inherits from OrthographicSystem:

typeof(attic) |> supertype

PolytonicGreek.GreekOrthography

So we can validate strings:

s = nfkc("έδοχσεν τôι δέμοι")
validstring(s, attic)

true

validstring("μῆνιν", attic)

false

And tokenize strings:

tokens = Orthography.tokenize(s, attic)
length(tokens)

3

tokens[1].tokencategory

LexicalToken()

tokens[1].text

"έδοχσεν"
