I'm running a Ubuntu Docker container. I have a Norwegian keyboard and need to use Norwegian characters (øæå).

My Terminal character encoding is set to UTF-8 and I'm connected to my container using SSH. However, I'm unable to type Norwegian characters, nor copy and paste Norwegian characters, nor use CTL+SHIFT+U+00f8.

I tried:

locale-gen nb_NO.UTF-8

but nothing changed. How do I set the locale and keyboard inside a Docker container?

Put in your Dockerfile something adapted from

# Set the locale
RUN sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen && \
ENV LC_ALL en_US.UTF-8     

this is extracted from the very good post on that subject, from

Setting Locale in Docker, In Docker container, usually the system locale was not set, and therefore UTF-8 could not be properly read and display in the terminal. In this blog  The lifetime of a container is the life time of its single main process. This forces every docker container to have a specific purpose and live by the unix maxima: “do this one thing, do it well”.

Those who use Debian also have to install locales package.

RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y locales

RUN sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen && \
    dpkg-reconfigure --frontend=noninteractive locales && \
    update-locale LANG=en_US.UTF-8


This answer helped me a lot.

I actually happened to have suffered from the same problem, but none of the provided answers are 100% working with debian:latest, even if they provide good hints.

The biggest difference is that you should make sure both locales and locales-all are installed, the latter already containing en_US.UTF-8, so you don't have to generate it with local-gen or dpkg-reconfigure.

Here's what I've done in my Dockerfile to make it work:
