title: How to convert ascii to utf8 with maven
body: <p>I have some generated classes, which are generated with ASCII encoding. But to compile this classes, the classes must be in UTF-8 encoding.</p>
  
  <p>So I need a plugin that converts this classes from ASCII or ISO-8859-1 respectivly to UTF-8.</p>
  
  <p>I tried to use the maven-resources-plugin and the native2ascii-maven-plugin to convert the files. But they didn't what I need.
  The maven-resources-plugin can only by configured with one  flag, that is used for reading input and writing output. I always use UTF-8. So it's obviously that it hasn't any effect.</p>
  
  <p>On the other hand the native2ascii-maven-plugin only converts in the wrong direction, namly from UTF-8 to ASCII. But I need to convert the files from ASCII to UTF8.</p>
  
  <p>Are there any other plugins or which plugin solves my problem? Which configuration I have to use? Please provide a definitely working configuration snippet.</p>
  
  <p>Thanks</p>
