Here it is a quick note to translate resource file (.properties) into Chinese:
1 - Edit i18n_bar.properties with your text editor.
2 - Translate values into Chinese.
3 - Save .properties with UTF8 encoding.
4 - Use native2ascii.exe available in JAVA_HOME/bin to convert UTF8 into UNICODE:
native2ascii.exe -encoding utf8 i18n_cn_orig.properties i18n_cn.properties
Try it.
