#### Escaping

Where the ABNF notes escaping, the following escaping MUST be applied Line feed, `\n` (0x0A) -> literally `\\n` (Bytecode 0x5c 0x6e) Double quotes -> `\\"` (Bytecode 0x5c 0x22) Backslash -> `\\\\` (Bytecode 0x5c 0x5c)
Where the ABNF notes escaping, the following escaping MUST be applied:
* Line feed, `\n` (0x0A) -> literally `\n` (Bytecode 0x5c 0x6e)
* Double quotes -> `\"` (Bytecode 0x5c 0x22)
* Backslash -> `\\` (Bytecode 0x5c 0x5c)

A double backslash SHOULD be used to represent a backslash character. A single backslash SHOULD NOT be used for undefined escape sequences. As an example, `\\\\a` is equivalent and preferable to `\\a`.

Escaping MUST also be applied to quoted UTF-8 strings.
