somebody said this bug is related to a config in /etc/fonts/conf.avail/89-ttf-thai-tlwg-synthetic.conf file, but that's not true. I does not have that package in my system and the not substitution problem appears.
A way to test that is to open an application like KeePass 2.x with some CJK characters in entries, all of them are being shown as empty squares.
