title: Mark words with special characters
body: <p>I have a list of about 1,300 IKEA products - this is an example of some of them:</p>
  
  <pre><code>läkt
  bigarrå
  bekväm
  blixt
  block
  blom
  bärbar
  bärby
  bästis
  bådalen
  bågvik
  </code></pre>
  
  <p>I'm trying to use a RegEx to mark those which contain "special" characters - e.g. anything other than simple lowercase a to lowercase z - such as:</p>
  
  <pre><code>läkt
  bigarrå
  bekväm
  bärbar
  bärby
  bästis
  bådalen
  bågvik
  </code></pre>
  
  <p>I tried this one:</p>
  
  <pre><code>[^a-z]
  </code></pre>
  
  <p>But it selects all of the words.</p>
  
  <p>I could do it if I were just using PHP, via the <code>ctype_alnum</code> function, but here I'm just using the TextPad or NotePad++ text editors.</p>
  
  <p>Is there any way to achieve this using a standard RegEx?</p>
