@jarey so what I just said. It shows the actually text for the HTML character code for %, and not the character itself in the composer textbox.
Correct, look at the composer side of the screenshot.
When you highlight text and click on one of the formatting buttons (bold, italic, etc.), strange things happen (but only on Edge and IE11):
Different things happen depending on how many words are selected. I've reproduced the behavior here on community.nodebb.org. I'd report this on github, but I don't know which repo is responsible...
@NedFodder you should report it here https://github.com/NodeBB/nodebb-plugin-composer-default
