+ * What is this?
+ *
+ * "This" is a preprocessor that makes an attempt to convert fully valid C++11 source code
+ * in utf-8 into something consumable by certain compilers (Solaris, xlC)
+ * which aren't quite standards compliant.
+ *
+ * - u"<unicode>" or u'<unicode>' gets converted to u"\uNNNN" or u'\uNNNN'
+ * - u8"<unicode>" gets converted to "\xAA\xBB\xCC\xDD" etc.
+ *   (some compilers do not support the u8 prefix correctly.)
+ * - if the system is EBCDIC-based, that is used to correct the input characters.
+ *
+ * Usage:
+ *   escapesrc infile.cpp outfile.cpp
+ * Normally this is invoked by the build stage, with a rule such as:
+ *
+ * _%.cpp: $(srcdir)/%.cpp
+ *       @$(BINDIR)/escapesrc$(EXEEXT) $< $@
+ * %.o: _%.cpp
+ *       $(COMPILE.cc) ... $@ $<
+ *
+ * In the Makefiles, SKIP_ESCAPING=YES is used to prevent escapesrc.cpp

+universal-character-name: \u hex-quad
+\U hex-quad hex-quad
+The character designated by the universal-character-name \UNNNNNNNN is that character whose character short name in ISO/IEC 10646 is NNNNNNNN; the character designated by the universal-character-name \uNNNN is that character whose character short name in ISO/IEC 10646 is 0000NNNN. If the hexadecimal value for a universal character name is less than 0x20 or in the range 0x7F-0x9F (inclusive), or if the uni- versal character name designates a character in the basic source character set, then the program is ill- formed.
