You have to watch out for the interactions with ASP, though. ASP has it's
own way of dealing with character encodings that is completely independent
of the XML technologies.
The key thing to watch out for is the Response.Write method. It always
abides by the "codepage" in effect, which is typically some variant of one
of the ISO-8859 set of encodings. To change this, you can explicitly set the
codepage and Content-Type header to do the right thing:
Response.ContentType = "text/xml; charset=UTF-8"
Alternatively, avoid using Response.Write. The "save" method on Microsoft's
DOM Document object ignores the ASP codepage and always uses UTF-8 (and sets
the Content-Type header for you) if you use the ASP Response object as the
parameter to that method. Likewise, if using XSLT, use the
"transformNodeToObject" method to invoke the stylesheet, and specify the
Response object as the second parameter, rather than using "transformNode"
in conjunction with Response.Write.
In deference to those who have chastised me in the past for responding to
Microsoft-specific questions on this list: if you have further questions,
you may want to ask in one of the Microsoft-specific newsgroups (such as
microsoft.public.xml or microsoft.public.xsl, which are publicly accessible
on the server msnews.microsoft.com).
