CKEditor: How to stop angle brackets from converting to HTML entities

Question

Our site is using tags like <# TAGNAME #> but CKEditor converts < and > to &lt and &gt which breaks these tags for use in our software.

I've discovered this option: config.protectedSource.push( /<#[\s\S]*##>/g ); which seems to stop the conversion if the data is saved from Source mode, but in WYSIWYG mode I can't find a way to stop the conversion. I've tried many options in their API but none of them seem to have helped, how can I fix this problem?

Answer 1

If you type < or > in any WYSIWYG editor, they will be converted to their HTML entities in source mode.
