The screenshots in selenium chrome node shows that Chinese characters display with square boxes. Install Chinese font could solve the problem.
add chinese font in base contaimer
Note installing fonts-noto-cjk will add 126.7 MB to the docker image, perhaps is better generating a separate image in this case.
Adding Chinese support is good. however not sure if those containers could accept such locale support for general cases. As different language may have different requrements
i'm going to keep this PR open just for reference, but i've assigned a milestone that i would like to achieve with these containers, and that is internationalization.
