title: Unmappable character for encoding ASCII but my files are in UTF-8
body: <p>I have the following error launching my ant script:</p>
  
  <pre><code>[javac] /****/TextUtils.java:25: error: unmappable character for encoding ASCII
  </code></pre>
  
  <p>But this file is encoded in UTF-8, if i do the info command:</p>
  
  <pre><code>/***/TextUtils.java: text/plain; charset=utf-8
  </code></pre>
  
  <p>Why is this file compiled in ASCII and not in utf-8?</p>
  
  <p>I tried to force the encoding in utf-8 on the javac command in my ant build file but without success</p>
