title: Regex for entering letters without emojis
body: <p>Is there any  examples of regex for entering text(letters) without emojis ?</p>
  
  <p>I tried to inverse regular expression but it works not correctly</p>
  
  <p><code>/(?!:\ud83c[\udf00-\udfff]|\ud83d[\udc00-\ude4f]|\ud83d[\ude80-\udeff])$/g</code></p>
  
  <p>In this case if I'm entering letters(<code>a-z</code>)  the string is not valid</p>
