How to change the subject info of Gmail into Chinese character?

Answer 1

Your string is a MIME RFC 2047 encoded word which can be decoded using PHP's mb_decode_mimeheader and mb_internal_encoding functions.

To convert your MIME encoded string to UTF-8, you can use the following code:

mb_internal_encoding('UTF-8');
echo mb_decode_mimeheader('=?GB2312?B?zbO8xtGnu/m0ocq10bXP7sS/?=');
