Function decode_entities 

pub fn decode_entities(input: &str) -> Cow<'_, str>

Available on crate features html and http only.

Decode HTML character references in input — all numeric references (©, ©) plus the common named ones (&, —, …).

Returns Cow::Borrowed when there is nothing to decode. Unknown or malformed references are left verbatim. This is the companion to escape/escape_into for consumers of the raw, undecoded text the tokenizer emits.
