What frequent use cases do you see where people will want to change bits rather than work with characters?

utf8_string str; str.reserve(some_big_number);

ifstream file("utf8.txt"); istreambuf_iterator<char8_t> begin(file), end;

std::copy( begin, end, back_inserter(str) );

This can't throw if you want people to use your string class.

And what if the example is changed to be: ifstream file("local8bit.txt"); istreambuf_iterator<char8_t> begin(file), end; std::copy( begin, end, back_inserter(str) ); ? This use case is common, so you have to provide something like "local8bit_back_inserter", and then to be explicit it's better to provide "utf8_back_inserter". - Volodya
