public class ValidateChars
extends DefaultHandler2

Command-line application that reads an XML file and checks its content against a predefined set of characters that are legitimate in a given language, reporting on anomalies. The purpose here is to find words that are misspelled or that are not encoded properly, so that they can be fixed in preparation for creating a word list.
