Hello,
Today the non latin characters entry in the right sidebar is still here.
After @vmassol had commented on this page How to remove an entry in the navigation bar when related page does not exist? - #10 by vmassol, related to strangely appearing foreign words in the right sidebar, I am coming again to report the same found foreign language as last time after I finished restarting XWiki post update : 샌드박스 테스트 페이지 1.
It still says in Corean : Sandbox Test Page 1
(in Debian VM with the latest 15.10.5 freshly updated XWiki edition).
Each time it occurs, only one entry is in a foreign language : either ukrainian, or in an asian language, or other non latin characters.
I have seen it occur several times along months of testings.
What should I make of it?
