-    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.

-    Conversions between UTF32, UTF-16, and UTF-8.  Header file.
-
-    Several funtions are included here, forming a complete set of
-    conversions between the three formats.  UTF-7 is not included
-    here, but is handled in a separate source file.
-
-    Each of these routines takes pointers to input buffers and output
-    buffers.  The input buffers are const.
-
-    Each routine converts the text between *sourceStart and sourceEnd,
-    putting the result into the buffer between *targetStart and
-    targetEnd. Note: the end pointers are *after* the last item: e.g. 
-    *(sourceEnd - 1) is the last item.
-
-    The return result indicates whether the conversion was successful,
-    and if not, whether the problem was in the source or target buffers.
-    (Only the first encountered problem is indicated.)
-
-    After the conversion, *sourceStart and *targetStart are both
-    updated to point to the end of last text successfully converted in
-    the respective buffers.
-
-    Input parameters:
-	sourceStart - pointer to a pointer to the source buffer.
-		The contents of this are modified on return so that
-		it points at the next thing to be converted.
-	targetStart - similarly, pointer to pointer to the target buffer.
-	sourceEnd, targetEnd - respectively pointers to the ends of the
-		two buffers, for overflow checking only.
-
-    These conversion functions take a ConversionFlags argument. When this
-    flag is set to strict, both irregular sequences and isolated surrogates
-    will cause an error.  When the flag is set to lenient, both irregular
-    sequences and isolated surrogates are converted.
-
-    Whether the flag is strict or lenient, all illegal sequences will cause
-    an error return. This includes sequences such as: <F4 90 80 80>, <C0 80>,
-    or <A0> in UTF-8, and values above 0x10FFFF in UTF-32. Conformant code
-    must check for illegal sequences.
-
-    When the flag is set to lenient, characters over 0x10FFFF are converted
-    to the replacement character; otherwise (when the flag is set to strict)
-    they constitute an error.
-
-    Output parameters:
-	The value "sourceIllegal" is returned from some routines if the input
-	sequence is malformed.  When "sourceIllegal" is returned, the source
-	value will point to the illegal value that caused the problem. E.g.,
-	in UTF-8 when a sequence is malformed, it points to the start of the
-	malformed sequence.
