Understand the syntax for escaping unicode code points and other characters in string literals.
What is wrong and why?
The Policy grammar page describes the string literal syntax as:
STR ::= Fully-escaped Unicode surrounded by '"'s
But it doesn't explain how to escape the unicode at all. Upon reading the Rust library source code, I found it somewhat surprising that the Rustic approach of \u{x...} is used which is somewhat different from many other libraries which use the fixed-width \uxxxx escape approach.
What do we need to do to fix this?
Document how to escape characters (a leading \) and what escape sequences are supported (n, r, u{...}, etc).
