In zh-wikipedia, We have simple Chinese and 
traditional Chinese converted with each other.
When a article were added to a category, it would 
automatically link to and included in a 
category,even if the  category name used are in 
different kind of words.

But from about Jaunary this year, things changed.If 
we use different kinds of words for category name 
in an article, the article will link to category, 
but won't included in the category.

We found that after any edit of the article,the bug 
will recover, but after refresh of data the problem 
appear again.

This is an example.The article 前550年（500 BC）  
[http://zh.wikipedia.org/wiki/%E5%89%8D550%E5%B9%B4]
links to the category:前6世纪（6th century BC in 
simplified Chinese），but in the category，the 
article dissappear（because in the article use
[[category:前六世紀]]in traditional Chinese） 

This problem made the categories for zh.wikipedia 
very unreliable.We hope it can be solved. Thank you 
very much.
