----------------------------------
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!
