title: Find the first occurrence with Regex
body: <p>I would like to be able to find the first occurrence of m² and then numbers in front of it, could be integers or decimal numbers.
  <em>E.g.</em></p>
  <blockquote>
  <p>&quot;some text&quot; 38 m² &quot;some text&quot; ,</p>
  <p>&quot;some text&quot; 48,8 m² &quot;some text&quot;,</p>
  <p>&quot;some text&quot; 48 m² &quot;some text&quot;, etc..</p>
  </blockquote>
  <p>What I have so far is:</p>
  <pre><code>\d\d,\d\s*(\m\u00B2)|\d\d\s*(\m\u00B2)
  </code></pre>
  <p>This right now finds all occurrences, although I guess it could be fixed with <code>findFirst()</code>. Any ideas how to improve the Regex part?</p>
