I think that the issue is that the HTML you want gets converted when you paste into the browser, so that stuff never gets to `raw`.
### Stuff from your fragment that you can see in raw
See https://meta.discourse.org/raw/189183/7
Here is some text. Font family = Calibri, size 12pt
This text is bold.
But if you copy the stuff from Word and then paste it, all of the HTML gets converted to markdown on the front end.
