title: HTML5 pattern allow specific special characters
body: <p>I have an input text field in my form but i don't know how to filter the input that can all letters and special characters but will not accept numbers. </p>
  
  <pre><code>   &lt;input  pattern="[A-Za-z]{1,25}" maxlength="25" type="text" required="required" style="height:20px"  value=""&gt;
  </code></pre>
  
  <p>It doesn't accept when i enter my middle name "pacaña"</p>
  
  <p>how could i alter the pattern that can accept all characters/special-characters and other special characters like ñ?</p>
