    Or to put it another way, XHTML-Print describes a single way of doing
    something. Wherease HTML and its derivatives frequently support multiple
    ways of getting the same effect.

    In the past, we have have resisted features that appear easy, unless they
    actually extend the capabilities of what can be done.

    Since I think a UTF-8 oriented client can get the same work done as a
    UTF-16 client, we should not mandate the extension.

    IMHO.

    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?
