Consider a case where a client sends a Print-Job request
with "utf-8" as the value of "attributes-charset" and with
the "job-name" attribute supplied. Later another client
sends a Get-Job-Attribute or Get-Jobs request. This second
request contains the "attributes-charset" with value
"us-ascii" and "requested-attributes" attribute with
exactly one value "job-name".
According to the IPP-Mod document (section 3.1.4.2), the
value of the "attributes-charset" for the response of the
second request must be "us-ascii" since that is the charset
specified in the request. The "job-name" value, however,
is in "utf-8" format. Should the request be rejected even
though both "utf-8" and "us-ascii" charsets are supported
by the server? or should the "job-name" value be converted
to "us-ascii" and return "successful-ok-conflicting-attributes"
(0x0002) as the status code?
