Comment (by Cigaes):

 Replying to [comment:4 beastd]:
 > I cannot exactly explain how all this works together, but it seems that
 you need to deal with another layer of escaping or in other words add
 another \ . Then it works as expected here.

 You escape once for the {{{drawtext=...}}} option and the parsing until
 the comma, and a second time for the {{{text=...}}} value and the parsing
 until the colon before fontfile.
