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? > > > > Van Dang > > My understanding: in this situation the Printer is required to convert > the job-name value from utf-8 charset to us-ascii.
