Hello Victor,

Thank you for your prompt answer.

> Which order do you expect? What is your OS? Result on Linux (Fedora 21) with the french UTF-8 locale.
You can try this ICU demo http://demo.icu-project.org/icu-bin/locexp?_=el&d_=fr&x=col and paste the list:

Ά
Γ
Η
Κ
Ν
Ο
έ
ί
α
β
γ
δ
ε
ζ
ι
κ
λ
μ
ν
ο
ς
τ
φ
χ
ό
ϐ
Ἀ
ῖ

You will get the same ordering as with Fedora, except the ῖ. It is a variant of i (corresponding to the letter i in Latin character). It should be sorted as an i and not just after Ἀ (the uppercase form of alpha) and before α (alpha).

May be this would be a good idea…

Kindest regards,
Pierre
