Re: [boost] [config] BOOST_NO_CXX11_HDR_CODECVT is not defined for VC14

[Andrey Semashev]

You can also see STL mentioning DevDiv#1060849 here: http://blogs.msdn.com/b/vcblog/archive/2014/11/12/visual-studio-2015-preview... and I can see that the problem is not fixed in RTM. This also concerns std::codecvt specializations for char16_t and char32_t. Can we define the BOOST_NO_CXX11_HDR_CODECVT macro for MSVC?

Investigating.... looks like a regression from VC12?

Technically, this isn't a regression because 2013 lacked char16_t/char32_t as real types. The STL (unwisely) provided fake typedefs. I need to figure out how to provide real char16_t/char32_t specializations, but this is not planned for any 2015 Updates. STL
