I use ZDT in Japanese and it works fine itself
However other people uses Outlook, Outlook Express, mobile phone, etc. and many mail client handles Japanese with ISO-2022-JP in default.
Therefore If other people reply/forward my mail, old generation mail client soft (many people using them) can not handle code set and can not read correctly
So I would like to change default code set of Zimbra Desktop to ISO-2022-JP.
Does anyone knows how to change it?
Thanks in advance.
