Reply To: Strange Characters Appearing in posts

Found it.

It’s the blank space characters causing the problem.

Likely, it’s happening through the WYSIWYG (Visual) editor in WP. Make sure to only add a single space after a sentence, not a double-space.

It appears to be a very old issue:

If you’re using any sort of plugins that enhance the post editor, this might also be the culprit.
