[Typo3] translation in extension's locallang utf-8

Woohoo... thanks to everyone the problem solved. !!

hopefully what i did here is correct, otherwise can someone comment?

Change default language of the website from english to chinese (the default language was english so no matter which chinese charset entered returned as junk characters), add language to page that contains the extension (this is to tell plugin to use CN value in extension's locallang?) 

config.linkVars=L
config.sys_language_uid = 0
config.language = cn
config.locale_all = chinese
page.config.language = cn
plugin.tx_srfeuserregister_pi1._LOCAL_LANG.cn.username = some text in chinese
plugin.tx_srfeuserregister_pi1._LOCAL_LANG.cn.password = some text in chinese
