-----Original Message----- [snip] These proposals are the Boost version of the TR2 proposals made in N3336, Adapting Standard Library Strings and I/O to a Unicode World. See http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3336.html. I'm very interested in hearing comments about either the Boost or the TR2 proposal [snip] -----Original Message----- Beman I do not understand how the converting c_str template can be useful in what for me, is the normal usage of the c_str function. Given existing code std::string stdstr; const char * cstr = stdstr.c_str(); third_party_api( cstr ); and moving to general use of a wide string type e.g. std::u32string stdstr; const char * cstr = stdstr.c_str< char >(); // ????????? third_party_api( cstr ); clearly it is possible to make third_part_api( stdstr.c_str< char
.c_str() ) work but surely that would also permit the above invalid use.
