I just saw that when looking at the code by myself. What do you exactly mean by a prefix tree?
I also noticed that the entity parser does not take into account combined Unicode characters (see §A.3 in: http://www.w3.org/TR/xml-entity-names/). In addition, even without entities, combined characters are displayed as separate ones.
