Actually, the XML spec states in section 2.2 that "A character is an atomic
unit of text as specified by ISO/IEC 10646" - in other words, Unicode.
Since there are different ways of storing Unicode characters, XML processors
are allowed to accept Unicode in any of these formats, and it even goes on
to state that "all XML processors <em>must</em> accept the UTF-8 and UTF-16
encodings of 10646" (emphasis added), since [I believe] UTF-8 and UTF-16 are
the most common ways to store Unicode characters. <aside>XML processors are
also allowed to <em>accept</em> data in any other encoding they want as
well, as long as the data is converted to Unicode. At least, I believe
that's how Microsoft reads the spec, because I had to study this crap at
great length and talk to Microsoft many times for my multi-lingual
application. :-) </aside>
Windows NT is perfectly Unicode aware, and I routinely view XML documents in
Notepad on my NT box. All of the characters are fine, with the only problem
being the LF-CRLF-CR problem that started this thread in the first place. I
am 87% sure that Windows 95 uses the windows-1250 or windows-1252 character
set internally, although it may also have some level of Unicode awareness.
(I'm not sure about that.) And I haven't the faintest idea what character
set Windows 98 uses natively, although I'd like to hope that it's Unicode.
