From 0a62fc5f6aafd3e3f67d861634014d7e894c7bfd Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Thu, 20 Jan 2011 07:31:58 +0000
Subject: Rework character reading functions to support reading multi-byte
 characters (take a string dest parameter instead of returning uchar). Escape
 ntriples output. Pass all good read tests with output verification.
