I have a solution where the html and document title is fetched by JSON as an object { 'title' : 'my title', 'body' : 'my html here' }. The single quote is returned as encoded \u0027 (') to avoid script errors. The telerik editor is now changing my single quote to " and breaking the html where ' is used? This has happend after an upgrade to latest version. I have tried changing ContentFilters="None" and ContentFilters="ConvertCharactersToEntities" - no change in behavior.
