I think that the best solution is to completely remove the restriction 
that XMLWriter will not write characters with values > 0XFF. If we 
support ISO 8859/1, UTF-8 and UTF-18 them we only have to use the 
numeric character encodings when we are using ISO 8859/1.

It's a common misapprehension with XML that the encoding restricts the 
characters that can be used. XML documents in *any* encoding can 
contain *all* of the Unicode characters allowed by the XML spec.
