Jenkins Console Print Encoded Characters

When outputting characters from a declarative pipeline running inside a linux container is it possible to change the encoding to match the true output from the terminal? I.e.

├── file1                         +-- file1
├── file2                         +-- file2
└── file3                         +-- file3

^Formatting I want                ^Formatting I get

.

I tried passing the following arguments to my Docker Agent:

-e JAVA_TOOL_OPTIONS="-Dfile.encoding=UTF-8" 

-e LC_ALL="en_US.UTF-8"

.

Combined with:

sh returnStdout: true, script: " "

And got ├── in place of the "+--", which seems to be the ANSI encoding for the "├──".

I am using the ansiColor Option but that didn't seem to help much.

.

I saw this similar question, but I was unsure on how to implement the solution in the pipeline.

For me, the problem was really in specifying the optional 'encoding' parameter to the 'sh' pipeline step: sh: Shell Script

Of course, this will only work provided the file.encoding is set properly as described in other posts here.

Here is the official answer from cloudbees. Unfortunately all of these did not work for me.

https://support.cloudbees.com/hc/en-us/articles/360004397911-How-to-address-issues-with-unmappable-characters-

Add these to JVM Arguments in master and also on agents -

-Dfile.encoding=UTF-8 -Dsun.jnu.encoding=UTF-8

You can use Jenkins II to change the encoding to UTF-8. Go to Jenkins -> Manage Jenkins -> Configure System -> Global properties

and add two envirenment variables JAVA_TOOL_OPTIONS and LANG having values -Dfile.encoding=UTF-8 and en_US.UTF-8 respectively

. enter image description here

After adding these you may need to restart Jenkins.

UPDATE:

or you can update <arguments> in jenkins.xml file. e.g.

<arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -Dfile.encoding=UTF-8 -jar "%BASE%\jenkins.war" --httpPort=8080 --webroot="%BASE%\war"</arguments>
