How do I disable smart quotes?

[Kenny Wyland]

When I'm typing and copy/pasting, I do not want Trello to change my normal quotes into smart quotes.

Smart quotes mess up so many things when I'm trying to copy and paste various things back and forth, etc. Just give me nice, simple ascii quotes. 

How can I disable the auto-replace so that it stop changing my normal quotes into smart quotes?
