Details:

Dear Sirs,

I have been using your marvellous product for sometime now and I have come
across a rather unusual bug.

It is supposed that Greek ISO-encoding is ISO-8859-7.
For some unknown reason from version 8.1 it is encoded as ISO-8859-6 which
is normally used by Arabic language and ISO-8859-7 produces Hebrew. It is
probably a one codepage shift left.

Please correct it or let me know what is really happening

Sincerely yours,
Nikolaos A. Papageorgiou
