 Priority:  normal        |   Milestone:  Awaiting Review            
Component:  General       |     Version:  3.0                        
 Severity:  major         |    Keywords:  chinese,tag,permalink,crawl
--------------------------+-------------------------------------------------
 If a TAG permalink have chinese (Japanese) characters, the permalink of
 the TAG is like this:"/tag/%E4%B8%80%E6%A0%B7/"
 [[BR]]
 In fact, the "%E4%B8%80%E6%A0%B7" is chinese (Japanese) characters. BUT,
 when a browser or a search engine spider visit or crawl the tag page
 /tag/%E4%B8%80%E6%A0%B7/, the wordpress3.0 will auto redirect
 "/tag/%E4%B8%80%E6%A0%B7/" to "/tag/%e4%b8%80%e6%a0%b7/".（lowercase）
 [[BR]]
 Then the problerm comes, a lot of Chinese and Japanses user report that
 when upgrade to Wordpress 3.0 the Google spider can NOT crawl there TAG
 page smoothly, the spider do not accept the 301, you can check the crawl
 errors and server log to see how the Wordpress give a 301 when hit the TAG
 url and how Google report errors.
 [[BR]]
 The Wordpress2.71 or 2.92 user does not have this problem. But
 Wordpress3.0 user will see a lot of redirect error in Google webmaster
 tool.
