I could find a decent forum module which allows to:
1. Lock threads
2. Manage permission (view, update, delete, etc.)
3. Use blessing of nodes (you do not have to repeat your modules functionality to work with comments)
4. Theme comments differently depend whether it's user profile, forum, different forum, etc.
I used nodecomments+categories to meet all requirements. The module actually automates the process of creating the hierarchy, and creates new buttons like "Add new thread" And New Topic", etc.
I heard that UTF encoding is not very good for Japanese or Chinese languages. I don't have enough information but the question is who this problem is solved in Drupal (in case this problem really exists)?
I wonder, did anybody try to develop web sites using these languages?
Over time, several have subscribed, and noted a few more forum posts discussing this as well.
I am hoping that someone can look into this issue and if possible, assign it to be addressed.
It seems that using mod_rewrite to set or modify the query string can corrupt it. One case where it certainly fails is if the URL has %2B (a urlencoded "+" character) in it.
