Script for text in rounded rectangle with image?

I got a following test to work, although a little differently.

#target illustrator
function test(){
  function centerTo(refObj, targetObj){
   var centerA, centerB;
   centerA = [(refObj.width / 2) + refObj.left, (-refObj.height / 2) + refObj.top];
   centerB = [(targetObj.width / 2) + targetObj.left, (-targetObj.height / 2) + targetObj.top];
   dX = centerA[0] - centerB[0];
   dY = centerA[1] - centerB[1];
   targetObj.translate(dX, dY);
  };
  function getSpecialCharacter(outlineObj){
  var thisCp;
  for (var i = 0; i < outlineObj.compoundPathItems.length; i++) {
  thisCp = outlineObj.compoundPathItems;
  if(thisCp.width >= 10.72 && thisCp.width <= 10.73 && thisCp.height >= 10.97 && thisCp.height <= 10.98){
  return thisCp;
  }
  }
  return null;
  };
  var doc = app.activeDocument;
  var t = doc.textFrames.getByName("Test");
  var dupe = t.duplicate(t, ElementPlacement.PLACEBEFORE);
  var dupeOutline = dupe.createOutline();
  var newSymbol = doc.symbolItems.add(doc.symbols.getByName("money-bag"));
  var specialChar = getSpecialCharacter(dupeOutline);
  if(specialChar == null){
  alert("Special Character not found");
  return;
  }
  centerTo(specialChar, newSymbol);
  dupeOutline.remove();
};
test();

The way I made this one work is, I configured my text frame text (named "Test" in the layers panel) to have an asterisk as the last character and I made it huge- big font size. I made sure to use subscript settings to some negative value to make the character come down on its baseline. I also made the rounded corner covnert-to-shape effect on a fill which was adjusted for relative width/height settings and also transformed vertically to be centered on the text. Then I outlined the text to manually record the width and height of the outline of the asterisk. Then in the code, I made the 'special character' be found on the condition that it is pretty much the same width/height as the shape. if(thisCp.width >= 10.72 && thisCp.width <= 10.73 && thisCp.height >= 10.97 && thisCp.height <= 10.98){

I also created a money-bag symbol in the document, and the script will put it on the artboard and center it on the asterisk outline.

Then the script removes the outline copy.

One thing I also did was color the asterisk character as the same background as the rounded rectangle- because since its subscript setting affects the size/position of the background, it was important to keep it in there and not remove it. So the asterisk is still there in the final result, but it is just not seen.

I think this could be solved potentially with the following technique:

You can have your text in a point text frame which has some spaces after it as well as some character which would be colored in a different spot-color. The character could be anything, like an asterisk, and the spot color could also be black, but with a different name. Then, a script can copy each of these text objects, outline that copy and then find the shape that is colored with your special spot-color. The location of the found shape is then recorded into memory and the copy is deleted, so that as a final step, the money-bag symbol is pasted and centered into the recorded location.

However, it would be even simpler if your money-bag art was already a font you use - then you wouldn't even need to do any scripting. If you can find a symbol font that is acceptable for your work, maybe some already have a symbol similar to this one.
