Ok this happens only when u create pages using DataAssist and without Templates.
If you use Templates and instruct DataAssist to enter the code into a specific Editable Region then cause the template page has UTF-8 encoding the pages are created properly.
Please fix DataAssist creationg process to use UTF-8 encoding cause many people don't use template system (including me) and using "includes" where they separate pages and main content and use variables to show content. If you use DataAssist as is for newly created pages then this product is only for websites that use "Western European" charset and not the most popular and same time should be always used UTF-8.
Please fix the default to be UTF-8 and give us a new Minor Release of DataAssist asap cause its really buggy for developers using "includes".
I checked DWCS4 default settings in case DataAssist uses DWCS4 settings but my settings are UTF-8 and still DataAssist ignores DWCS4 settings completely when creating new pages. Please fix it so it uses DWCS4 default settings so people depending on their default Dreamweaver settings have their pages created as they want.
