How could I print the Chinese correctly?

[ouyunwen]

I print some chinese words into the file using log4j2. When I want to see the content of file by using "tail" ,I found that all of the chinese words in the file are “???”.

@ouyunwen The default encoding of character set in Log4j2 is utf8, which covers Chinese characters. (See Log4j2 layout). To root cause your issue, can you check the encoding in log4j configuration and the actual content of your log file?

Another possibility might be tail modifying the charset of the terminal. See post.

Let me know if this works for you.

I solved the problem by creating a new custom docker image afterwards.
I created a new docker file base on centos,and added chinese component,and change the timezone to Shanghai.
The whole content of the docker file as follows:

FROM centos:latest

I ran into the same issue. The strange thing is that e.g. OpenJDK sets default encoding to UTF-8 in their images (https://github.com/docker-library/openjdk/blob/master/8/jdk/Dockerfile#L21). The result was that I had an app that was running perfectly fine on OpenJDK but failing on Corretto.
