/** \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.
