title: replacing mutated vowel form a string
body: <p>I'm looking for a nice way of replacing all mutated vowel within a string by their &quot;unmutated&quot; vowel(combinations).</p>
  <p>Basically it is like:</p>
  <pre><code>&quot;ä&quot; -&gt; &quot;ae&quot;  
  &quot;ö&quot; -&gt; &quot;oe&quot;  
  &quot;ß&quot; -&gt; &quot;sz&quot;  
  &quot;Š&quot; -&gt; &quot;S&quot;  
  &quot;ć&quot; -&gt; &quot;c&quot;  
  </code></pre>
  <p>and so on ...</p>
  <p>I know I could create a map for this and do it maybe with a loop to replacing all occurrences but that looks awful.
  Further I have to create a complete mapping likst form &quot;mutated&quot; to &quot;unmutated&quot;.</p>
  <p>Is there a more elegant way in Java to do so?</p>
  <p>Note: I have to support Java 1.8</p>
