title: Is there Simple way to use String.toLowerCase() for 9 kinds of languages?
body: <p>I need to treat 9 kinds of language in a list below.</p>
  
  <ul>
  <li>Dutch</li>
  <li>English</li>
  <li>French</li>
  <li>German</li>
  <li>Italian</li>
  <li>Portuguese</li>
  <li>Russian</li>
  <li>Spanish</li>
  <li>Ukrainian</li>
  </ul>
  
  <p>For words in these languages I need to use <code>tolowercase()</code>.
  and I know I need to use <code>Locale(country, language)</code> as a parameter of the function.
  Then, do I have to use specific locale for each language, or is there simpler way to do this? </p>
