Concerning a Greek client I have:
I have saved the names of the subscribers in Greek (as the names are greek).
Whenever I personalise my messages' subject eg. Γιάννης, Your February Newsletter - I have problems on the subject line.
When this is sent, the name that is in Greek Characters does not appear correctly but in a format such as:
%AC%E3... Your February Newsletter
Is there a way to fix this?
