>            std::back_inserter(result)

> Now we have utf8 encoded string in result container. That’s all.

> Library contains implementation for following transformations/algorithms: 
> utf7, utf8, utf16(be/le), utf32(be, le), Unicode simple folding, base64, 
> rc5(cipher/decipher).
> Library allows creating pipeline converters, e.g.:
>
> typedef cvt::encoder<char, char> coder_t; // char to char sequence 
> transformation
> coder_t coder = cvt::utf7() >> cvt::utf16() >> cvt::utf8() / cvt::int8() 
>  >> cvt::rc5<32,12,8>(key) / cvt::int8() >> cvt::base64();
>
> That expression defines pipeline transformation. Utf7 encoded sequence 
> transforms to utf16 encoded sequence, then to utf8 encoded, then performs 
> rc5 cipher with specified key, then performs base64 encoding.
