#### Newline Normalization
Literal Newline sequences in Multi-line Strings must be normalized to a single
`U+000A` (`LF`) during deserialization. This means, for example, that `CR LF`
becomes a single `LF` during parsing.
This normalization does not apply to non-literal Newlines entered using escape
sequences.
For clarity: this normalization is for individual sequences. That is, the
literal sequence `CRLF CRLF` becomes `LF LF`, not `LF`.
