So my question is why does this work and displays dots :
<Field label="Password" value="•••••" type="password" />
And the above just displays the plain hexa code !
<Field label="Password" value={`${'•'.repeat(10)}`} type="password" />
My Field component :
function renderValueByType(value: string, type: string) {
  switch (type) {
    case 'phone':
      return phoneFormatter(value);
    default:
      return value;
  }
}
/**
 * 
 * @param {*} param0 
 */
const Field = ({ label, value, type, className }: PropTypes) => (
  <div className={className}>
    <span className="Field__label">{label}</span>
    <span className="Field__content">{renderValueByType(value, type)}</span>
  </div>
);
                If you set a static string as a prop it will be rendered as is.
If you set a variable as a prop it will be sanitized.
Your best bet here is convert your hex char code to string before passing it down to your component (using String.fromCharCode()):
<Field
   label="Password"
   value={String.fromCharCode("0x2022").repeat(10)}
   type="password"
/>
