| \page status_of_cpp0x_characters_support Status of C++0x char16_t/char32_t support |
| |
| The support of C++0x \c char16_t and \c char32_t is experimental, mostly does not work and not |
| intended to be used in production with current latest compilers: GCC-4.5, MSVC10 till major |
| compiler's flaws would be fixed. |
| |
| \section status_of_cpp0x_characters_support_gnu GNU GCC 4.5/C++0x Status |
| |
| GNU C++ compiler provides decent support of C++0x 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++0x 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++0x requirements making it impossible to write \c char16_t/char32_t to stream |
| and causing multiple faults. |
