Printing binary string as character?

Hi everyone,

I'm really sorry if this is a basic question, but I have been searching for hours and found nothing.

I am trying to turn a string into binary data and then convert it back into characters. The code for turning it into a string of binary numbers was pretty easy, so I would imagine that it would be similarly easy to turn it back into characters.

Code for string to binary:

String myText = "Hello world";

     for(int i=0;i<myText.length();i++){
        String out;
        char myChar = myText.charAt(i);
        for(int i=7;i>=0;i--){
          int num = bitRead(myChar,i);
          delay(100);
          out += num;
        }
        Serial.println(out);
      }

I have tried countless methods to try and print "out" as a character, but none seem to work.
Have I missed something? Is there a way of doing this?

From reading around other posts it seems you're supposed to print it as a char, but that only outputs numbers, not the letters I originally put in.

Many thanks,
Sam

char myText[] = "Hello World";
int numOfChars = sizeof(myText) / sizeof(myText[0]);

void setup()
{
  Serial.begin(115200);
  for (int c = 0; c < numOfChars - 1; c++)
  {
    Serial.print(myText[c]);
    Serial.print(" : ");
    for (int b = 7; b > 0; b--)
    {
      Serial.print(bitRead(myText[c], b));
    }
    Serial.println();
  }
}

void loop()
{
}
