I have successfully installed language support for Chinese language through Language Support > Install Remove / Languages ... > Chinese (simplified).

While I am testing multi-language support for my application, I wanted to test some stuff with support for certain language and without system supporting the language.

After removing Chinese the same way I installed it, my system now continues to correctly display Chinese characters even if Chinese support is uninstalled. So my testing is now paused, I want to figure out what else was installed and not uninstalled with me clicking check-box and uninstalling Chinese (simplified).

What else should I uninstall, may be some fonts or other stuff? Is there any way to find out what packages each language check-box installs in Ubuntu Language Support to make it universal, because after Chinese I am moving to other languages too?

I did logout, reboot, to make sure settings are applied, did not help. I am adding relevant /var/log/dpkg.log

Output of locale command:

  • Please show us the output of the locale command. – Gunnar Hjalmarsson Dec 14 '15 at 16:39
  • @GunnarHjalmarsson I appended my question with locale command. – Mike Dec 14 '15 at 17:33
  • Ok.. So, what is the actual problem, then? I can tell you that any Ubuntu system has the ability to display Chinese characters, since the fonts-droid package is installed by default, whether the dedicated Chinese support packages have been installed or not. – Gunnar Hjalmarsson Dec 14 '15 at 18:02
  • That is not true, I have several default 15.10 desktop installations updated and upgraded to this date running now here in one room and only those with Chinese installed display characters correctly, I am talking about filenames in Nautilus and Nemo, standard characters in Firefox and Chrome .... if not installed, then it is showing rectangles instead of characters. – Mike Dec 14 '15 at 20:07
  • So what about the presence of the fonts-droid package?`It's a recommended package in the ubuntu-desktop package, and hence installed automatically when installing Ubuntu 15.10. – Gunnar Hjalmarsson Dec 14 '15 at 20:21

In /var/log/dpkg.log I found that fonts-arphic-uming and fonts-arphic-ukai are installed with Chinese language pack and they are not uninstalled when language pack is removed.

sudo apt-get purge fonts-arphic-ukai
sudo apt-get purge fonts-arphic-uming 

Removing these two packages returned Ubuntu to it's original setup.

  • Good that you figured out what you were after. Your description, that fonts-droid (i.e. Droid Sans Fallback) isn't sufficient to display Chinese characters, confused me. Still does, actually. – Gunnar Hjalmarsson Dec 15 '15 at 0:51
  • @GunnarHjalmarsson I was testing only unicode supplementary characters as they are important for my application to work, so standard characters are displayed fine. I am new in this area, so I have a checklist and proceed, but these supplementary characters may be part of person's name and other important stuff, I want them to work. – Mike Dec 15 '15 at 8:01
