MathML rendering doesn't work for symbols like Pi, Alpha,... #1

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Evaluate a symbol like "Pi" in pretty printer mode

What is the expected output? What do you see instead?

It's expected to see the MathML output for "Pi" but instead it throws 
exception:

Caused by: org.xml.sax.SAXParseException: The entity "pi" was referenced, 
but not declared.
