\page status_of_cpp0x_characters_support Status of C++11 char16_t/char32_t support

The support of C++11 \c char16_t and \c char32_t is experimental, mostly does not work, and is not
intended to be used in production with the latest compilers: GCC-4.5, MSVC10 until major
compiler flaws are fixed.

\section status_of_cpp0x_characters_support_gnu GNU GCC 4.5/C++11 Status

GNU C++ compiler provides decent support of C++11 characters however:

-# 	Standard library does not install any std::locale::facets for this support so any attempt
    to format numbers using \c char16_t or \c char32_t streams would just fail.
-#	Standard library misses specialization for required \c char16_t/char32_t locale facets,
	so "std" backends is not build-able as essential symbols missing, also \c codecvt facet
	can't be created as well.

\section status_of_cpp0x_characters_support_msvc Visual Studio 2010 (MSVC10)/C++11 Status

MSVC provides all required facets however:

-# 	Standard library does not provide installations of std::locale::id for these facets
	in DLL so it is not usable with \c /MD, \c /MDd compiler flags and requires static link of the runtime
	library.
-#	\c char16_t and \c char32_t are not distinct types but rather aliases of unsigned short and unsigned
	types which contradicts to C++11 requirements making it impossible to write \c char16_t/char32_t to stream
	and causing multiple faults.

If you want to build or test Boost.Locale with C++11 char16_t and char32_t support you should pass `cxxflags="-DBOOST_LOCALE_ENABLE_CHAR32_T -DBOOST_LOCALE_ENABLE_CHAR16_T"` to `b2` during build and define `BOOST_LOCALE_ENABLE_CHAR32_T` and `BOOST_LOCALE_ENABLE_CHAR32_T` when using Boost.Locale
