.RS 4
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 \fIunusual\fP character types\&. Also, check out include/ext/pod_char_traits\&.h\&.
