> Yes, but I thought using the glyph instead of the NCR was not valid XML?
Glyphs are pictorial representations of a character (as produced by
fonts, typically) You don't mean glyph here. in XML you can use any
character that is in the specified encoding. So if you are using ASCII
for example you can use "A" as a character directly, or as A
But you can't enter an e-acute or an em dash directly as they are not in
the encoding so you have to use an NCR for them. UTF8 on the other hand
encodes eery character so you can always use character data directly (or
you can use NCR if you want)
> Glyphs are what you are reading right now,
But they are not what is in an XML file.
The shapes I see on my screen depend on the shapes specified in the
fonts that I am using.

As you are finding, characters, glyphs and encodings can be confusing,
it's best to keep the different layers clearly distinguished.
You might want to look at
http://www.w3.org/TR/2003/WD-charmod-20030822/
which distinguishes these in some detail.

No, XSLT will use character data (in most implementations) not NCR if
you ask for utf8 encoded output (or accept that as the default). To force
NCRs to be used, specify an encoding such as US-ASCII that does not
contain the characters.
> it's false. — is not ASCII data, is it?
Yes, it is. that bit of your message contains 6 bytes of information.
You want me to understand it as
ampersand-hash-eight-two-one-two
I can only do that if I know that the bytes represent letters in ascii
(or an ascii compatible encoding) that is what the xml encoding
declaration is for. It does not specify the underlying character set,
there is no need to specify that as it is _always_ unicode in an XML
context..

It's how XSLT works, which is quite logical once you get to grips with
the meaning of an encoding declaration in XML.
