----------------------------------

             Summary: PatternLayout's default charset should not be UTF-8
                 Key: LOG4J2-783
                 URL: https://issues.apache.org/jira/browse/LOG4J2-783
             Project: Log4j 2
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.1
         Environment: Win8(Simplified Chinese), Tomcat 7
            Reporter: Minglei Lee


According to log4j2's manual about PatternLayout's charset attribute, if the attribute is not specified, the default system Charset will be used.

But in my environemnt (Win8 Simplified Chinese + Tomcat 7), if the attribute is not specified, the Chinese words cannot display properly in console. If I add charset="UTF-8" to console's PatternLayout, the error still exists. But if I modify it to charset="GBK", the problem can be resolved.

So I think, The default charset is UTF-8, not the default system Charset as the manual announced. I got the source file, and found it in PatternLayout's Builder inner class: 

private Charset charset = Charsets.UTF_8;

I modify it to:

private Charset charset = Charset.defaultCharset();

and remove the charset attribute in XML's PatternLayout element, the Chinese words can display properly as expected.

So, I think it may be a bug and reported it here.

Thanks!
