I tried to use Rich edit-free but did not work with the Veronika theme, the producer says it's an old plug-in. We found this premium HTML Editor plugin here: https: //market.osclass.org/plugins/text-processing-wysiwyg-editors/html-editor_453.
Does anyone know if it works with the theme of Veronica not to buy it for nothing?

I did not have chance to test it. If it use iriginal text area fields, there will be no problem.
