[aricb] HTML character entity references are defined as part of the HTML specification: http://www.w3.org/TR/REC-html40/sgml/entities.html
The following code defines two commands, htmlentities::insertentities and htmlentities::removeentities. The first command replaces Unicode characters with HTML character entity references; the second command replaces HTML character entity references with the literal Unicode characters they represent. There's nothing fancy about the code, but hopefully it's useful to somebody.
