Yuki,


Formally, we can allow any character set allowed by the whole ISO 10646
standard over the IPP protocol, not only the UNICODE subset. Does that
solve your problem? My expectation though, is that nobody will actually
support the full ISO 10646 in a workstation. If the USA and Europe supports
Unicode, is there another subset that you would implement in Japanese or
Chinese language workstations?
