Hi to all.
Is there any chance, fix the Greek letter sigma on case conversion action on your next release.
example:
original name file: ΜΙΧΑΛΗΣ ΧΑΤΖΗΓΙΑΝΝΗΣ - ΤΟ ΚΑΛΟΚΑΙΡΙ ΣΟΥ.mp3
converted name file: Μιχαλησ Χατζηγιαννησ - Το Καλοκαιρι Σου.mp3
correct name file: Μιχαλης Χατζηγιαννης - Το Καλοκαιρι Σου.mp3
When the letter starts or contains a Sigma (Σ) then the case conversion is correct (Σ). However when the letters ends with Sigma (Σ) then the conversion should be with "final" S so it should be with "ς".
thank you

I do not think that MP3tag has a specialized table for capital and small characters.
So if you are not satisfied with the current results, you could add 2 actions to the action group that effects the case conversion.
One to (simply) replace "σ " with "ς "
and one with a regular expression to replace
"σ$" with "ς"

Replacing "σ " with "ς " it was enough to do the trick.
Thank you
