Special characters not being displayed properly inside text editors on a docker container

Question

I'm trying to display these Special Characters,µß£¬, on my Docker Container running java-centos' vi editor and nano editor, but the ß character is replaced with sort of a question mark � instead.

expected output: µß£¬ actual output: µ�~_£¬.

But I can echo these characters on the terminal?!?! So it's just to do with the editors not being able to display the ß character.

I've tried all the suggestions from changing the default locale from POSIX to C.UTF-8 to setting the locale to German, to no avail.

Dockerfile:

FROM nimmis/java-centos:oracle-8-jdk
ENV LANG C.UTF-8

Answer 1

Okay so I've got it to work by adding this line to the Dockerfile, it's to do with the locale not being set properly on Centos7.

ENV LANG en_us.utf-8
