[xwiki-users] Cannot deal with Chinese tags on XWiki-7.3

I create a new tag named "运营” But, it displays just like rubbish, And I can not remove it nor rename it. I think the problem is in "tag=è¿%C2%90è%C2%90¥" encodings. If I manually input the URL with "tag=运营"， the actions goes well, but display still be bad. …/xwiki/bin/view/Main/Tags?do=viewTag&tag=è¿%C2%90è%C2%90¥ …/xwiki/bin/view/Main/Tags?do=viewTag&tag=运营 The expected display should be like below: My browser is Safara 9.0.1 under Mac.
