[jira] [Commented] (LOG4J2-783) PatternLayout's default charset should not be UTF-8

Remko Popma commented on LOG4J2-783:
------------------------------------

You are right, thanks for pointing this out.
Looks like this is a regression for LOG4J2-255. PatternLayout should use the platform default encoding, but when the builder was introduced it started to use UTF8 again. We'll fix this in the next release.

>             Project: Log4j 2
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 2.0.1
>         Environment: Win8(Simplified Chinese), Tomcat 7
>            Reporter: Minglei Lee
>              Labels: charset, default
>   Original Estimate: 72h
>  Remaining Estimate: 72h

> 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> element, 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!
