## Detailed Description

### template<class _CharT>
struct std::char_traits< _CharT >

Basis for explicit traits specializations.

Note
  For any given actual character type, this definition is probably wrong. Since this is just a thin wrapper around __gnu_cxx::char_traits, it is possible to achieve a more appropriate definition by specializing __gnu_cxx::char_traits.

See https://gcc.gnu.org/onlinedocs/libstdc++/manual/strings.html#strings.string.character_types for advice on how to make use of this class for unusual character types. Also, check out include/ext/pod_char_traits.h.
