Hello,

Consider this XML:

<!DOCTYPE math PUBLIC "-//W3C//DTD MathML 3.0//EN"
"http://www.w3.org/TR/MathML3/dtd/mathml3.dtd">
<math xmlns="http://www.w3.org/1998/Math/MathML">
        <mi>π</mi>
        <mo>⁢</mo>
        <msup>
          <mi>r</mi>
          <mn>2</mn>
        </msup>
 </math>

I cannot get the value "π" because TXMLReader.ParseRef as far as I
can tell will substitute it with an empty string =(

How can I get "π" or at least the Unicode char for Pi? Maybe I
should add a field to allow me to define my own ParseRef routine? This
way I could in my own code fix this. I guess I could change ParseRef
to substitute π with pi, but this could lead to an endless amount
of combinations which could be valid.... and all of them need to be
added to ParseRef.

thanks,
