Hi Peter –
Hope you are well. Thanks for getting in touch.
The Public Post Preview plugin doesn’t work with Gutenberg.
There’s a built in preview option with Gutenberg. Have you tried using it already? It’s in the upper right corner of the menu near the gear icon.
Is there a specific function of that plugin that you’re using?
where can I easily access the special character menu? This is also critical for creating written content.
Great point! It’s not there from the testing that I did. I’ll file it as an enhancement in Github for the team.
There’s a work around that you can use though. Not super easy, but not terrible either.
Figure out the html for the characters that you use often. This page should help with that: https://dev.w3.org/html5/html-author/charref
The html can be added anywhere with in the posts, blocks, pages, etc on the site. Just switch over to the code editor view.
Find the three vertical dots in the upper right corner of the editor, click those dots, click on the Code Editor option, add the html for the special characters.
I hope that helps.
