This was due to a broken deployment of Parsoid, the new MediaWiki parser used by VisualEditor. A new library dependency defaulted to iso8859-1 instead of utf-8, which caused character munging to occur.
Gabriel is working on a postmortem and we'll share this shortly with recommendations on how to avoid such an incident in future. We're very sorry for the breakage. Affected edits likely have already been reverted - but if there's anything in addition we can do, let us know. The team is still actively investigating the issue on #mediawiki-visualeditor on irc.freenode.net, which is the best place to reach them.
