title: Detect strings with non English characters in Python
body: <p>I have some strings that have a mix of English and none English letters. For example:</p>
  
  <pre><code>w='_1991_اف_جي2'
  </code></pre>
  
  <p>How can I recognize these types of string using Regex or any other fast method in Python?</p>
  
  <p>I prefer not to compare letters of the string one by one with a list of letters, but to do this in one shot and quickly.</p>
