Javascript WYSIWYG textarea plugins produce inconsistant results across browsers?

I'm in need of a lightweight, Javascript-based, WYSIWYG editor that transforms <textarea>s into Rich Text Editors. There are thousands of these plugins开发者_开发百科 out there (and I feel like I've demoed them all). For reasons outside of my control, I need the editor to produce legacy HTML... so it needs to write <b> instead of <strong> or <span style=...>.

Fine. No problem. There are plenty of these that purport to do just that. Here's the weirdness though: I'm finding that in a ton of these editors that I've played with, they output different things in different browsers! Chrome will output <b> but Firefox will output <span style="font-weight:bold">?!

For example, try applying bold in these editors in both Chrome and Firefox:

See? <b> in Chrome, but <span style="font-weight:bold"> in Firefox. Weird!

Any ideas?

Instead of searching for the less known editor, you should have started with the most commonly used ones like CKEditor and TinyMCE.
