Since the integration of the new Editor in SPP5 we have had more and more issues regarding strange text formatting on multiple systems. After some research it turns out: When copy & pasting from MS Word the HTML is not properly filtered and lots of style information is kept in the editor. While this is a common issue with WYSIWYG-Editors, we did not have this problem for YEARS now since JCE Editor filters input without any problems (or at least has the possibility to explicitly set this in the settings).
I know, it would be possible to switch to the System Editor before pasting Text from Word, but i'm honestly tired of explaining to my clients, that the process of editing their website has become even more complicated again....
Please add an option to filter out MS Word HTML completley or filter it out by default since it would usually make no sense at all to paste styling information into any text editor input in SPPB.
