Example
1, A UTF-8 string from the socket.
int len = ::recv(sd, buf, buflen, 0);
textbox.caption(nana::charset(std::string(buf, len), nana::unicode::utf8));
2, Send the string in text to the socket as UTF-8.
std::string utf8str = nana::charset(textbox.caption()).to_bytes(nana::unicode::utf8);
::send(sd, utf8str.c_str(), utf8str.size(), 0);
3, Convert a string to the specified multi-byte character code.
//Convert to a multibytes string through default system language.
std::string mbstr = nana::charset(a_wstring);
//If the default system language is English and convert
//a Chinese unicode string to multibytes string through GB2312
std::setlocale(LC_CTYPE, "zh_CN.GB2312"); //set::setlocale(LC_CTYPE, ".936"); call it in Windows
std::string mbstr = nana::charset(a_wstring_with_chinese);
