  Wrong, sorry, see the spec ! 

    http://www.w3.org/TR/REC-xml#NT-Char

 &x10800; is perfectly legal and should be viewed as a single character
for example in XPath expressions. This doesn't mean that you have
to change your internal encoding, but you need to make sur the wrappers
for all the access computing length etc. are doing the computation right.

  Eric's problem can probably be solved technically by simply providing
such a wrapper function.
