Ok, with that we know that the fontconfig settings make a difference also for KDE/QT apps.

Hmm.. I have a test installation of Kubuntu which I upgraded to try to reproduce the problem. I couldn't.

Sure, if I uninstalled fonts-droid, those squares showed up when viewing a piece of Chinese text with Kate, but with fonts-droid the text seemed to be rendered normally. (Please see attachment.) So I can't help wondering if fonts-droid was installed when you tested on your VM.

Another thing struck me: The list of Droid fonts at
https://launchpadlibrarian.net/178980889/select%20system%20font.png
is much shorter than the list I saw in the font select window (see attachment). Especially I miss Droid Sans Fallback, which is essential for CJK languages.

Can you please ensure that the fonts-droid package is completely installed on your existing installation by running

sudo apt-get install --reinstall fonts-droid

Can you also post the output of the command

fc-match -a 'sans-serif'
