 Why is it that if you save a unicode sequence in a file, say "français"
~ 
\u0066\u0072\u0061\u006e\u00e7\u0061\u0069\u0073
~ 
 and then retrieve as a String you can't then convert it back to a UTF-8 String
~ 
 As you can test with this piece of code, you can simply declare the String as
a literal one or give it in the command prompt, but retrieving what seems to be
the same sequence of characters (as they print to standard out) from a file 
doesn't seem to work

import java.io.ByteArrayOutputStream;
import java.io.PrintStream;
import java.io.UnsupportedEncodingException;
import java.io.IOException;

// __ 
public class UniKdEnk00Test{
 private static final String aNWLn = System.getProperty("line.separator");
// __ 
 public static void main (String[] aArgs){
  try{
// __ 
   if((aArgs == null) ||  (aArgs.length != 1)){ throw new IOException(aNWLn + 
"// __ usage:" + aNWLn + aNWLn + 
" java UniKdEnk00Test \\u0066\\u0072\\u0061\\u006e\\u00e7\\u0061\\u0069\\u0073"
+ aNWLn);  }
   String aUniKdEnk = "\u0066\u0072\u0061\u006e\u00e7\u0061\u0069\u0073";
   byte[] bAr = aUniKdEnk.getBytes("UTF-8");
   ByteArrayOutputStream BOS = new ByteArrayOutputStream();
   BOS.write(bAr, 0, bAr.length);
   String aUTF8L = new String(BOS.toByteArray(), "UTF-8");
   System.out.println(aUTF8L);
   BOS.reset();
  }catch(UnsupportedEncodingException UEncX){ UEncX.printStackTrace(); }
    catch(IOException IOX) { IOX.printStackTrace(); }
// __ 
 }
}
