Forumlar / Cotonti / Extensions / anyone help me?

I like this cms,but i found that the url of tags has been "urlencode" twice,then it makes a problem.

for example,my tag "测试"（means "test" in chinese）

based on this cms,its url is "plug.php?e=tags&a=pages&t=%25E6%25B5%258B%25E8%25AF%2595"

but the url should be "plug.php?e=tags&a=pages&t= %E6%B5%8B%E8%AF%95",which would work correctly.

so,what can I do now?

or,can anybody tell me where to edit the detail of "{INDEX_TAG_CLOUD}",then I may found a solution myself.

thank u very much!
