Hi Perry,

in general actioncache should work with any encoding, no matter whether 
it's unicode or not. Anyway there are some places where your encoding 
could get screwed up:

If response.getOutputStream() is called, the cached data is written to 
disk using a FileOutputStream byte by byte (assuming it's binary data). 
If on the other hand response.getWriter() is called, the cached data is 
written to disk using a FileWriter. Since no encoding is passed to the 
FileWriter, the default system encoding will be used. Please make sure 
<code>new FileWriter().getEncoding()</code> returns "UTF-8" and note 
that since JDK 1.4.2 the JVM doesn't honor the file.encoding system 
property anymore.

Kind regards,
Felix
