I'm used to a few hacks when using MathJax code in my pagedown to stop some characters being interpreted as special instructions (e.g. sometimes escaping underscores), but I can't seem to get \left{ to work (\left[ and \left( do). Escaping the brace doesn't work... what can I do instead?
I'm using pagedown in a Mezzanine project on Django/Python 3.
