[xsl] Recognized Unicode characters?

["Edward Bryant" <bryant_edward@xxxxxxxxxxx>]

Hello again,

I am having a problem getting my XSLT transformation to read the correct 
Unicode reference for an em-dash ( — ). I get that little square box 
in place of the correct character in the output when I use instant Saxon, 
but when I let IE6 handle the transformation it works fine.

I take it that instant Saxon cannot read an em-dash?

Is there a reference of what characters it does read?

How do I display and em-dash correctly?

Isn't this a problem for portability between XSLT processors?

--Or am I just not doing something right?
