title: Ehcache cache .data files have escaped unicode characters
body: <p>My caches' data filenames seem to contain escaped unicode characters in the data store. Strangely only capital letters in the cache names are replaced. Eg:</p>
  
  <blockquote>
    <p>%004c%004f%0043%0041%004c%004dodifier%004cinking%004danager.data</p>
  </blockquote>
  
  <p>Should be:</p>
  
  <blockquote>
    <p>LOCALModifierLinkingManager.data</p>
  </blockquote>
  
  <p>Why is this the case? How can I fix it?</p>
  
  <p>Environment: Windows 7 x64</p>
