codecvt Class
A template class that describes an object that can serve as a locale facet that is able to control conversions between a sequence of values used to encode characters within the program and a sequence of values used to encode characters outside the program.
For a list of all members of this type, see codecvt Members.

class codecvt : public codecvt_base
Parameters
CharType
The type used within a program to encode characters.Byte
A type used to encode characters outside a program.StateType
A type that can be used to represent intermediate states of a conversion between internal and external types of character representations.
Remarks
The internal encoding uses a representation with a fixed number of bytes per character, usually either type char or type wchar_t.
As with any locale facet, the static object ID has an initial stored value of zero. The first attempt to access its stored value stores a unique positive value in id.
The template versions of do_in and do_out always return codecvt_base::noconv. The Standard C++ Library defines an explicit specialization, however, that is more useful:
template<> codecvt<wchar_t, char, mbstate_t>
which converts between wchar_t and char sequences.
