+   Conversions between UTF32, UTF-16, and UTF-8. Source code file.
+   Author: Mark E. Davis, 1994.
+   Rev History: Rick McGowan, fixes & updates May 2001.
+   Sept 2001: fixed const & error conditions per
+   mods suggested by S. Parent & A. Lillich.
+   June 2002: Tim Dodd added detection and handling of incomplete
+   source sequences, enhanced error detection, added casts
+   to eliminate compiler warnings.
+   July 2003: slight mods to back out aggressive FFFE detection.
+   Jan 2004: updated switches in from-UTF8 conversions.
+   Oct 2004: updated to use UNI_MAX_LEGAL_UTF32 in UTF-32 conversions.
+
+   See the header file "ConvertUTF.h" for complete documentation.
