Right, just to clear things up, is the 7.1 PM issue fixed in 7.1.1 for users with special characters in their display names?
It is NOT fixed in 7.1.1
Or is converting to UFT-8 the only way around this bug for the time being?
This IS the fix, until a way can be devised to convert all old posts to UTF-8 this will not however be pushed out.
