Title: v1 headers are encoded as UTF-8 Status in OpenStack Image Registry and Delivery Service (Glance): Won't Fix Bug description: In the v1.1 API, metadata headers are echoed with the values encoded as UTF-8 (since bug 1042078). However, UTF-8 is not a valid encoding for HTTP header values. (Indeed, some ASCII characters are also forbidden.) The output should be encoded using the MIME header encoding rules from RFC 2047 (http://www.ietf.org/rfc/rfc2047.txt ). For reference the format of the header field contents is defined in section 4.2 of RFC 2616: field-content = <the OCTETs making up the field-value and consisting of either *TEXT or combinations of token, separators, and quoted-string> http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2 ...which must be further interpreted using section 2.2: The TEXT rule is only used for descriptive field contents and values that are not intended to be interpreted by the message parser. Words of *TEXT MAY contain characters from character sets other than ISO-8859-1 only when encoded according to the rules of RFC 2047. TEXT = <any OCTET except CTLs, but including LWS> http://www.w3.org/Protocols/rfc2616/rfc2616-sec2.html#sec2.2 The Location: header is a special case, since its value is a URI, which needs to be URL-encoded (this brings it into the acceptable subset of ASCII, and therefore no further encoding is required). (A similar issue in python-glanceclient is bug 1108969. The encoding of these headers is treated differently on reception, as described in bug 1108979.)
