Since Wygwam 2.3.1 it's supposed to have "Set the forcePasteAsPlainText CKEditor config setting to 'Yes' by default" (pasted from release notes). But I'm still getting a lot of junk code (inline styles, Word markup, the whole shebang).
Is this happening for other people as well? I've even tried adding it manually as a config setting, but that didn't make any difference.
Any help would be greatly appreciated, as this is making my client's life miserable.
