Форумы / Cotonti / Support / Textboxer?

Yes. It's in UTF-8 and has utf-8 collation, but datas was always inserted with an iso-8859-1 server, so... I would convert all datas, with many many problems...
And I think it's not a good introduction to Cotonti and it's default texteditor to force all webmaster to this step (in particular those that don't need multilingual functionalities for their websites). And someone can explain me why fckeditor doesn't have this preview problem? So, it's not a charset problem only...

And nobody answer me why automatic refresh in preview doesn't go well... it's a bad integration of markitup in Cotonti?
