Unicode to char* c++ 11

I want to know if is there any way to convert a unicode code to a string or char in C++ 11. I've been trying with extended latin unicode letter Á (as an example) which has this codification:

letter: Á
Unicode: 0x00C1
UTF8 literal: \xc3\x81

I've been able to do so if it's hardcoded as:

const char* c = u8"\u00C1";

But if i got the byte sequence as a short, how can I do the equivalent to get the char* or std::string 'Á'?

EDIT, SOLUTION:

I was finally able to do so, here is the solution if anyone needs it:

std::wstring ws;
for(short input : inputList)
{
    wchar_t wc(input);
    ws += wc;
}
std::wstring_convert<std::codecvt_utf8<wchar_t>> cv;
str = cv.to_bytes(ws);

Thanks for the comments they were very helpful.

The C++11 standard contains codecvt_utf8, which converts between some internal character type (try char16_t if your compiler has it, otherwise wchar_t) and UTF-8 encoding.

The problems is that char is only one byte length, while unicode characters require a size of two bytes.

You can still treat it as char*, but you must remember that you are not dealing with an ascii string (there will be zeros).

You may have to switch to wchar_t.
