From RFC3629(http://tools.ietf.org/html/rfc3629#section-6):
o A protocol SHOULD forbid use of U+FEFF as a signature for those textual protocol elements that the protocol mandates
tobe always UTF-8, the signature function being totally useless in those cases.
COPY explicitly specifies the encoding (to be UTF-8 in this case). So
I think we should not regard U+FEFF as "BOM" in COPY, rather we should
regard U+FEFF as "ZERO WIDTH NO-BREAK SPACE".
