but not collation. The problem here was that text literals in a view were always dumped with character set introducer. That lead to loosing collation information. The fix is to dump character set introducer only if it was in the original query. That is now possible because there is no problem any more of loss of character set of string literals in views -- after WL#4052 the view is dumped in the original character set.
