japanese email subject encoding

Question

Aparently, encoding japanese emails is somewhat challenging, which I am slowly discovering myself. In case there are any experts (even those with limited experience will do)

Answer 1

=?ISO-2022-JP?B?TEXTTEXT...

ISO_2022-JP means that string is encoded in ISO-2022-JP codepage (eg. not Unicode) B means that string is bese64 encoded

In your example, you should just supply your string in ISO-2022-JP instead of Unicode.
