I'm trying to post HTML content pages (e.g. syllabus) that contains HTML entities such as html5 checkmarks (✓). The content posts successfully, but the leading "&" is expanded server-side to "&and", I think. I've taken a look at the JSON I'm posting and it seems the entities are unexpanded in that file. Is there a standard trick for avoiding this? otherwise I guess I will have to just remove these characters from my syllabus, is that right?
