Regex: Replacing the first character with lower case character
<p>Consider this piece of text(four spaces between words):  </p>

<pre><code>word    Word  
word    Word  
word    Word
</code></pre>

<p>I'm using Notepad++.  </p>

<p>I search for: <code>\b    (\w)</code><br>
I want to replace with:  <code>&nbsp;\l$1</code></p>

<p>When I click <kbd>Replace</kbd> button, no replacement is done with the text above, but with this text it works fine (four and two spaces between words):  </p>

<pre><code>word    Word  
word  Word  
word  Word  
</code></pre>

<p>Is this because of Notepad++?</p>
