Hi, I sometimes get the following error in xwiki (0.9.840) when I try to browse a category (e.g. KidsCorner in the following). It is related to some invalid characters in the wiki content but I usually paste some useful content into our wiki and don't know what character is forbiddern. Is there a way for us to avoid problem like the following. It made all the pages in the category not browsable and is very inconvenient. Now what I have to do is to manually go to the postgresql database to modify some table content and it doesn't always work. Have you guys encountered similar problem and is there a better solution to fix/avoid it?
