I am working on a chinese version of WordPress. Everything was working great until I found out chinese username is not supported. It was important to show chinese username because many chinese users prefer to be identified by their chinese monikers in either their posts or comments. I was trying to hack WP functions, like santize_user. But after looking at the code, I dont think it was a good idea to change any WP core functions because it is obvious WP is not built to be fully UTF8 compatible. I understand there are issues like portability. So to make things simple for myself, I now decide to use nickname as the author name because users can input chinese in the nickname field. I hope u guys can help me out here. I need to find out how I can modify "comments.php" to display nickname for comments. I know it is an easy job to display nickname for posts.
Million thanks in advance!
