My server is used Centos 7.
After following the instructions on this How to fix "perl: warning: Setting locale failed" , when access SSH through root doesn't see any error:

However, I still see the following error message when access through Jailed Shell:
-----
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = "UTF-8",
LANG = (unset)
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
----

Is it because Cpanel sets locale differently and it's per application and more complex?
How can I fix this? Please help me.
