Working with huge chunks of formatted text?

Working on a text-based game in HaxeFlixel, and I’m wondering if there’s a best practice for dealing with the text itself. There’s a lot of it, and it’s full of newlines and quotes and such. I imagine putting it in the actual Haxe script is probably not the best way, since you’d have to use a zillion escape characters? So like maybe a Markdown file where you could tag each text block something appropriate, and then parse it from Haxe?
