How to install additional languages in Kubuntu 16.04 LTS?

Question

I need my system to be able to display the characters of Chinese, Japanese, and Right-To-Left languages like Arabic. At the moment, it is not able to display the characters of those languages (e.g. the names of the files that are written in those foreign characters).

Having said that, I still want my main input method and my system language to be in American English.

I have tried to look for language support in the settings, but couldn't even the find the entry. Any solutions or suggestions would greatly be appreciated. Thanks.

After several days of researching, I found out the following:

Step 1: Open your terminal and type:

sudo apt install language-selector-gnome

Step 2: Open the language selector using your terminal:

gnome-language-selector

Step 3: Install the required the languages that you need then reboot your system and enjoy the new list of added languages. You might also need to install additional fonts depending on your requirements.
