+/** \File 
+ * Provides basic utility functions to convert between
+ * the various Unicode character conversions. There are of
+ * course various packages that could be used instead of these
+ * functions, but then the Antlr 3 C runtime would be dependant
+ * on the particular package. Using ICU for this is a good idea if
+ * your project is already dependant on it.
