Why is %E2%80%8F being added to my Youtube embed code?
I can't believe that this fixed it! And, you are a true gentleman to give the bounty/answer to Tudor. Also, thinking back to how I created the id in the first place, it was copy/pasted directly off of a Youtube link; so, if this does happen again, and I'd like to keep using my editor, the quick solution seems to be to just manually type in the Youtube video id instead of copy/pasting it.
