Make document's character encoding reflect byte-order marks #5359
Merged

This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

This change fixes a bug where document's character encoding was set to the return value of the encoding sniffing algorithm rather than to the actual encoding used, which differed when the stream started with a byte-order mark. This change incorporates BOM sniffing into the encoding sniffing algorithm, ensuring both encodings are identical. Closes whatwg#1077.

The process of decoding the network byte stream to Unicode is backed by an instance of `encoding_rs::Decoder`, which will switch the encoding it uses if it finds a BOM in the byte stream. However, this change in encoding is not communicated back to the caller and so `document.characterSet` gives the wrong result. This change fixes that. See whatwg/html#5359 and whatwg/encoding#203 for the spec-level backing for this change.
