title: Does Ruby or Rails have a method to capitalize the first character only?
body: <p>Or it seems like I have to write my own method?  (to keep the <code>DHA</code> untouched):</p>
  
  <pre><code>ruby-1.9.2-p180 :001 &gt; s = 'omega-3 (DHA)'
   =&gt; "omega-3 (DHA)" 
  
  ruby-1.9.2-p180 :002 &gt; s.capitalize
   =&gt; "Omega-3 (dha)" 
  
  ruby-1.9.2-p180 :003 &gt; s.titleize
   =&gt; "Omega 3 (Dha)" 
  
  ruby-1.9.2-p180 :005 &gt; s[0].upcase + s[1..-1]
   =&gt; "Omega-3 (DHA)" 
  </code></pre>
