Detailed Description

An intelligent charset class for character code conversion. 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);

Examples:

widget_show.cpp, and widget_show2.cpp.
