pub fn transcode_to_utf8(bytes: &[u8]) -> Result<Cow<'_, [u8]>, XmlError>Expand description
Detect the encoding of bytes and transcode them into UTF-8.
For UTF-8 / US-ASCII input the result is Cow::Borrowed (zero copy).
For Latin-1 / Windows-1252 it is Cow::Owned — these encodings produce
UTF-8 about 1.0–1.5× the input size.
Does not verify that the inner <?xml ... encoding="X" ?> declaration
agrees with the encoding detected from the bytes — for that, use
transcode_to_utf8_strict.
