Hi Matthew, please don't roll back the content of the english wiki, as it doesn't have utf-8 characters in the titles, and there have been quite some changes this week. We are starting the opensuse board elections today, and use the wiki as platform for the candidates for example.
I have verified that it doesn't contain UTF8 in the titles and is safe to continue. It will NOT be rolled back, and I have removed the lock on it. An interesting thing I noticed is that the English wiki has a different collation on the page table than the other wikis. It is a new wiki, unlike the others, which have been upgraded from much earlier versions. That may be a clue as to the root cause and how we can fix it. The other wiki that is new, of course, is the German wiki. It has the same collation on the page table as the English wiki, and it is different than the old German wiki and all the other wikis. Guess which UTF8 wiki isn't broken?
Also for the other wikis I hope there comes up a patch so we can fix the page titles without losing the new edits. I think there also have been some changes in the german wiki at least. It looks like the German wiki is actually fine, for the reasons mentioned above. I'll remove the lock on it soon. I'm working hard on saving the others. I think the Russian wiki may be a lost cause, but I haven't lost hope yet.
