Note that Coptic has its own block, with the few characters in Greek block due to prior unification. Implementing this would entail also implementing the whole Coptic script (in principle).

I remember once there was an issue about Coptic (or extended Greek) and I decided to exclude them and align them with the real Coptic block.
