[HACKYSTAT-DEV-L] byte array to text, any expert?

[(Cedric) Qin ZHANG]

Hi,

I am working on the SVN sensor. I can get any revision of any file 
stored in SVN through an OutputStream, which essentially means I get a 
byte array of contents which I don't know it's text or binary.

Even for text, they can be encoded in ASCII, Unicode, UTF-8, etc. My 
question is:

(1) Is there a way in Java to tell between binary and text content from 
a byte array?

(2) If I know that  a byte array contains text  content, how  do I 
convert them  into an array of Strings, each representing one line.

byte[] inputs = .....  
BufferedReader reader = new BufferedReader(new InputStreamReader(new 
ByteArrayInputStream(inputs)));
   String line = reader.readLine();
   while (line != null) {
     System.out.println(line);
     line = reader.readLine();
   }

What I find the above code can only handle ASCII encoded text file 
successful, the output is messed up with unicode. Any experts?

Thanks.
