Hi,

i am using latest version of wordpress with buddypress and theme my login, all are in chinese locale.

the issue was, when a user registers at my site, activation email wasnt being sent. after some digging, i found out that the email title is all garbage character (seems like chinese chars are not properly handled), so my email is consider spam and not sent.

SMTP error from remote mail server after end of data:
550 High probability of spam

Subject: =?UTF-8?B?W2hvdyB0byB2YW5dIOa/gOa0u+aCqOeahOW4kOaItw==?=

as you can see, the subject field is not properly populated.

so my question is:
1) how to update the buddypress activation subject? If i really want to use chinese, how should i properly encode it? If it cant be done, how to change it to all english?

2) i would more prefer the second way. right now buddypress somehow overwrites theme my login activation email functionality. how can i use the theme my login activation functionality instead of the buddypress one? With theme my login, i can easily manage email text.

thanks in advanced!
