TinyMCE completely mangles any rich text pasted into it, it mangles it beyond recognition. It mangles it so horribly that it is almost impossible to edit it manually after the fact, and it introduces weird formatting that makes the user look like a complete moron. Don't just take my word for it, I can show you an example.

The following text exists on my computer and it looks exactly like this in the word processor.

Fledgling time travelers looking to travel in style are advised to seek out a police box, as a Delorean cannot be sourced anywhere other than another time traveler. By 2015 there isn't a single authentic Delorean or police box left on earth, although there are still hundreds of police boxes that can be rescued before their destruction.

Evolution

Throw out everything you know about human evolution for the purposes of this game. In this universe humans never evolve on any significant level. The people of another time may look collectively different, but not so different that any one individual from one time would look out of place in another time.

The reason for this decision is not based in any particular beliefs on evolution, but is instead done because it allows the characters to visit and interact with other humans from the earliest cavemen to the last people in the universe.

The various hominid species all existed in the past, and indeed some similar species exist in some future time, but basic modern humanity endures from far before recorded history all the way to the end of the universe. The hominid species are related but distinctly different species.

Ok, looking good so far, well, the formatting looks good (only used paragraph tags and a single set of bold tags), the text itself was questionable!! But what does TinyMCE do with this text?

Where the heck did all those extra line breaks come from? Lets look at the source code.

Wow, what a nightmare. I know html and I can barely read that. It is specifying the font all over the place, even right in the middle of words. It would be easier to start over from scratch manually than to try to edit that mess.

This my friends is why you shouldn't touch TinyMCE with a ten foot pole.
