Expected behavior is that the separating comma remains a plan comma. This can result in the address header being misinterpreted by some mail servers.</p> <p><strong>Affected:</strong> Python Software Foundation CPython</p> <p>During an address list folding when a separating comma ends up on a folded line and that line is to be unicode-encoded then the separator itself is also unicode-encoded.
