…rted bytes CTEs Failed content setup, such as an unknown charset, can discard an existing message's content or leave its parent converted to multipart. Restore the original headers and payload when a content handler raises, and prepare new parts before converting their parent while preserving conversion error precedence. Reject unsupported bytes content-transfer encodings with ValueError instead of emitting an unrecognized Content-Transfer-Encoding header.
