i have problem about chinese characters. i don't known why some chinese characters cannot be show correctly, but others is ok. the ss version i'm using is silverstripe-v2.2.2-rc5.

when i post content from ss, i found the data in mysql had been not all correct yet.
when i post content through phpmyadmin, data in mysql is all ok, but in ss still have the problem.
when i post content from the demo in silverstripe.com, everything is ok.

could anyone tell me how to solve this problem?

thanks a lot.
