Regarding Chinese characters, I believe that system-wise there is display support for Japanese and Simplified Chinese but not Traditional Chinese characters; Just to be safe I threw in a full Unicode font to solve the problem and gain other character sets for the browser.
Thanks, I didn't notice, because my Chinese tags all use simplified characters. Japanese seems to be fine, though, and Kanji mostly resemble traditional Chinese or look a little different than their Chinese origin. So maybe traditional Chinese is supported as long as the same characters are used for Kanji by the system.
