    Jim:

    I would disagree. I don't believe that all XHTML-Print enabled printers
    will necessarily bite the bullet and include a complete XML parser that
    requires support for UTF-16. I don't believe we should force that to
    occur. Perhaps you should remind the group that XHTML-Print is target for
    LOW-END printers with this embedded. No 3 gigahertz Pentium 4's with 512
    MB of memory!!!

    I tend to agree with Henri when he says that support UTF-16 would not be
    much more expensive than UTF-8. Does anyone on this list or the PWG's
    XHTML-Print list disagree?
