How to create new translations of the SVN edition?

Hi
The translation is not adequate in SVN 11329 and the translation status on Launchpad remains full. So I modified the data/supertuxkart.pot file by myself (adding new lines as "%1 flattens %0" and "Story Mode", etc) using VIM and added some Chinese translations in zh_CN.po using poedit . However, it does not work properly. Some Chinese characters does not show.
