The patch is attached. This attribute is rarely used in HTML but the interesting functionality is encoding character bodies of generated requests into bytes according to the specified encoding.
If you try to click() a form specified as <form method="POST" enctype="multipart/form-data"> with some Unicode data in its fields you will get this error: HTTP::Message content must be bytes at blib/lib/HTTP/Request/Common.pm line 91 My patch fixes that by always encoding wide characters to the encoding specified in "accept-charset" attribute or set via method. Defaults to utf-8. Avoids unneeded encodings. Also, caution taken not to break compatibility with older perls. Docs and tests included.
