Binary to UTF-8 in C

I am working on an application in C where I need to show Unicode UTF-8 characters. I am getting the values as a binary byte stream as 11010000 10100100 as character array which is the Unicode character "Ф".

I want to store and display the character. I tried to convert the binary to a hexadecimal character array. But printing with

void binaryToHex(char *bData) {    char hexaDecimal[MAX];    int temp;    long int i = 0, j = 0;    while (bData[i]) {        bData[i] = bData[i] - 48;++i;    }    --i;    while (i - 2 >= 0) {        temp = bData[i - 3] * 8 + bData[i - 2] * 4 + bData[i - 1] * 2 + bData[i];        if (temp > 9)            hexaDecimal[j++] = temp + 55;        else            hexaDecimal[j++] = temp + 48;        i = i - 4;    }    if (i == 1)        hexaDecimal[j] = bData[i - 1] * 2 + bData[i] + 48;    else if (i == 0)        hexaDecimal[j] = bData[i] + 48;    else        --j;    printf("Equivalent hexadecimal value: ");    char hexVal[MAX];    // size_t len = j+1;    int k = 0;;    while (j >= 0) {        char *ch = (char*)hexaDecimal[j--];        if (j % 2 == 0) {            hexVal[k] = '\\';            k++;            hexVal[k] = 'x';            k++;        }        printf("\nkk++Length %d ...J= %d.. ", k, j);        hexVal[k] = ch;        k++;        printf("%c", ch);    }    printf("KKKK+=== %d", k);    hexVal[k] = NULL;    // printf("\nkk++Length %d",strlen(hexVal));    printf("\nMM+-+MM %s===\n ..>>>>", hexVal);}

Only showing the value as \xD0\xA4. I did string manipulation for that.But when writing in the way

 char s[]= "\xD0\xA4";         OR char *s= "\xD0\xA4"; printf("\n %s",s);

producing the desired result that is printing the character "Ф". How can I get the correct string dynamically? Is there any library for this in C?

The code is from http://www.cquestions.com/2011/07/binary-to-hexadecimal-conversion-in.html.

Is there a way to print it from binary directly or from a HEX value. Or is there an alternative for that?
