DelimitedString:
	q" Delimiter WysiwygCharacters MatchingDelimiter "

Therefore you can choose you delimiter, which as you say might be " Also 
it looks like you can't use any escapes, because it says 
WysiwygCharacters above.

and further down:

Wysiwyg Strings

Wysiwyg quoted strings are enclosed by r" and ". All characters between 
the r" and " are part of the string except for EndOfLine which is 
regarded as a single \n character. There are no escape sequences inside 
r" ":

I take that to mean that you can't use escapes in DelimitedStrings, either.

This would be quite useful for regex, for example.
