According to rfc9112 quoted string is defined by rfc9110

quoted-string = <quoted-string, see [HTTP], Section 5.6.4>

The definition of quoted-string also uses a notion of quoted-pair:

quoted-pair    = "\" ( HTAB / SP / VCHAR / obs-text )

This change makes the parsing of quoted-string aware of quoted-pairs and makes it possile to handle valid quoted strings.
