is there any that runs on the server side that allows you to save the format (somehow) to the database along with the content?

Something like this
<script>
function captureIt(cap,field) {
  if (cap) {
    field.style.display='none'
    document.getElementById('output').style.display='';
    document.onkeydown=function(e){
      e=(e)?e:event;
      if(!e)return 0;
      field.value+=String.fromCharCode(e.keyCode);
      document.getElementById('output').innerHTML=field.value
    }
  }
  else document.onkeydown=null;
}  
</script>
 
<input type="text" onFocus="captureIt(true,this)">
<span id="output" style="display:none"></span>
