title: Generate javadoc for classes that have non-ascii charaters in their names
body: <p>Some of the classes in our code base have Unicode (Danish) characters in their names. It works fine for compilation and deployment, but it failed when generating Javadoc complaining about wrong characters in the java sources. We are using Gradle to build our code base and the following options actually solved the problem with wrong characters:</p>
  
  <pre><code>  javadoc {
      options.encoding = "UTF-8"
    }
  </code></pre>
  
  <p>But that still fails on finding classes that have non-ASCII characters in their names:</p>
  
  <pre><code>javadoc: error - File not found: "E:\Work\source\common\my-integration\src\main\java\my\company\vehicle\common\K├©ret├©jListeHentValidationHelper.java"
  </code></pre>
  
  <p>Is there any workaround for that?</p>
