/*
 * Ok, here's a small Qt-based program that shows how to override the default
 * string encoding.  This one just uses utf8, but I think it's clear how one
 * would proceed based on this.
 *
 * I would also recommend by default (i.e. when ISO-8859-1 is selected) not
 * using an external string handler at all since they extra lookups will
 * likely slow things down.
