Conventional string literals
Conventional string literals are enclosed in double quotes (
They support the same escape sequences as in C++ programming language (
Raw string literals
Raw string literals are enclosed in paired single quotation marks: characters
How to type this symbols see here.
If raw string should contains unpaired single quotation marks, then balancing of raw string should be performed like as for raw HTML in pq markup (see Advanced formatting. Raw HTML).
For example, there is a string
It contains unpaired closing single quotation mark. Let's add a balancing opening single quotation mark at the beginning of the string: ‘don’t.
Enclose that balanced string in single quotation marks: ‘‘don’t’.
Now we need to somehow show to the parser that single quotation mark at the beginning of the string is not a part of the raw string [it is needed only for balancing]. For this purpose typewriter apostrophe
'is used: one apostrophe absorbs one single quotation mark. In our case one apostrophe should be added at the beginning of the string:
This balanced string can be put inside another raw strings as is:
‘text = '‘‘don’t’’.
