+ 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: , ,
+ or 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.
