stdlib - UTF8 console i/o in Windows, other crucial stdlib fixes, functional area headers

stdlib is a pure header library that provides
  • fixes for some standard library issues, including that <stdlib/console_io.hpp> makes Windows console i/o work for international text such as Norwegian (more precisely the Basic Multilingual Plane of Unicode is supported for the iostreams objects such as cout), with narrow text encoded as UTF-8;
  • C++ library header wrappers for all C++ standard library headers, e.g. you can just include <stdlib/iostream.hpp> where you want the <iostream> header with the Windows console i/o fix, plus some;
  • C library header wrappers, e.g. <stdlib/math.hpp> which for maximal portability includes both <cmath> and <math.h> for you, and ditto for the other C library headers;
  • functional area headers for the C++ standard library, e.g. just include <stdlib/io.hpp> to get all the C++ iostreams headers plus the C standard library’s i/o headers, more precisely all headers in this category mentioned in the header overview at cppreference.com; and
  • extensions such as <stdlib/byte_to_wide_converter.hpp>, which provides the class that’s used for narrow and wide encoding conversion in the Windows console i/o fix. Most of the extensions are part of the library implementation anyway, so they’re provided in a reusable form in the public interface. Those that are not directly used in the current library code, are provided for completeness.
Other fixes & nice-to-haves include
  • support for de facto standard <math.h> constants such as M_PI;
  • support for the C++ standard’s alternative keywords such as and, or and not, in Visual C++;
  • random seed for C++11 random number generation with g++;
  • support for output of something that converts implicitly to wchar const*, on a wide stream, corresponding to how something that converts implicitly to char const* can be output an a narrow stream;
  • setting the default locale in C and C++ to the user’s native locale, which makes the wide iostreams work for international text in *nix-land;
  • setting UTF-8 as the basic execution character set (i.e. for narrow literals) in Visual C++; and just because it’s nice to have in a portable way,
  • support for ANSI escape sequences, e.g. to produce colored console text or move the text cursor on the screen, in Windows 10 and later.

Operating Systems

Compilers

  • Visual C++
  • GCC
  • Any standard C++ compiler
