Ugly hack: add this before loading transliterator:

\startluacode
unicode = unicode and unicode or _G
\stopluacode

I get the following output:

kakon anagkē, all' udemia anagkē zēn meta anagkēs

I hope this helps. I also think you should mail Philipp so that he fixes it (the Lua code looks pretty old).

Cordially,

Jairo

I tried the MWE example below with the transliterator module, but context throws an error:
token call, execute: ...ules/tex/context/third/transliterator/transliterator.lua:20: attempt to index a nil value (global 'unicode')

\usemodule[transliterator]
\starttext
\transliterate[mode=gr]{κακὸν ἀνάγκη, ἀλλ' οὐδεμία ἀνάγκη ζῆν μετὰ ἀνάγκης}
\stoptext

I'm using context current version: 2021.10.24 21:45

Is the Transliterator module from Philipp Gesang what you're looking for?
