[NTG-context] List of special characters

I can’t find a definitive list of the special characters that I need to ‘escape’ when used in a ConTeXt document. I’m writing a short script that converts documents, and I need to catch some characters. Some of the TeX ones I tried didn’t work. Couldn’t see it in the manuals. I’ve done the obvious ones - \%, \#, \&, \$ - but wondering about some of the others (eg ! \" # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _ ` { | } ~ • º). thanks!
