Description of problem:

Red Hat OpenJDK 11 docker image doesn't have LANG env.

LANG=en_US.UTF-8

Since this is not available in the Image some users are not able to use the Special Characters inside the container environment, as the special character is not visible and a "?" is coming at the place of special character.

Version-Release number of selected component (if applicable):

How reproducible:
Always

Steps to Reproduce:
1. Pull an Red Hat OpenJDK 11 image
2. Use that image to build a specific application which may include a special character in the code.
3. Check the special characters in the code, those will not be visible.

Actual results:
Special characters are not visible.

Expected results:
Special characters should be visible properly, LANG=en_US.UTF-8 should come as the output of ENV inside container's shell.
