Email contents are not recognizable!

[SinaBina]

Hello
Using YAF for past two years I have recently (After updating to latest version of SVN) been reported that emails sent to users such as from PM or Registration are not recognizable and sometimes are in Chinese!
Forum is in Arabic.

Example:

Known issue that does need to be resolved. Unfortunately, it's a bit of work to fix.

I think it is a critical bug specially for forums with lots of SPAM activity.

That issue was causes because the emails where not correctly encoded. This issue is fixed in YAF 2.1
