used with the Standard C++ Library 2.1.1. Note that the earlier Tools.h++ library version
7.0.6 could not be used with -AA.
UTF-16 Character Transformation Format Support
The current compiler supports only ASCII strings or characters (8 bit chars with no
transliteration) as UTF-16. UTF-16 is described in the Unicode Standard, version 3.0
[UNICODE]. The definitive reference is Annex Q of ISO/IEC 10646-1 [ISO-10646].
Any string or character which is preceded by ‘u’ is recognized as a UTF-16 literal or character
and is stored as an unsigned short type.
Example:
#define _UTF16(x) u##x
#define UTF16(y) _UTF16(#y)
typedef unsigned short utf16_t;
utf16_t *utf16_str = UTF16(y); // u”y”
