Detailed Description

ERXNSPrintWriterLogger is an alternative of NSLog.PrintStreamLogger but accepts character oriented java.io.PrintWriter instead of byte oriented java.io.PrintStream so that the character encoding for logging can be explicitly set.

Usage:

 // Create a PrintWriter with Japanese "SJIS" encoding. 
 OutputStreamWriter sjisOutWriter = new OutputStreamWriter(new FileOutputStream("app.log"), "SJIS");
 PrintWriter sjisPrintWriter = new PrintWriter(sjisOutWriter, true);

 // Create a logger then set it to NSLog.
 NSLog.Logger logger = new ERXNSPrintWriterLogger(sjisPrintWriter);
 NSLog.setDebug(logger);
 NSLog.setOut(logger);
 NSLog.setErr(logger);
