I am happy to report that our tool has been updated to support unicode characters. Please see Example 1 on the main page for a demonstration of using α as a symbol.

A new javascript based webpage is now the default. It is hoped to offer a better user experience. It has been tested on firefox, opera, and internet explorer. Let us know your feedback. The old interface is available at http://www.adiff.com/cgi-bin/adiff.pl
