ARCH GNU/Linux Ker. 4.6.2-1 x86_64
I think it is something wrong with the Tcl/Tk interface and its interaction with the XServer on UNIX machines. Maybe a conflict/incompatibility with the freetype2 libraries and Tcl/Tk. I had located a strange passing of arguments inside the /*Altera_install_DIR*/modelsim_ase/tcl/vsim/fonts.tcl file.
In the X11 section it queries the pkgconfig for specific font packages, specifically : (sans-serif && monospace) or (Helvetica && courier). Also it sets the sizes with a negative sign (i.e. -12, -14 etc.) contrary to the MS Windows or OSX sections. On proper editing of these lines nothing happens, wchih leads me to believe this is not an actual control file, nevertheless it seems an installation of the Helvetica font may prove beneficial for further inquiries. Tomorrow I will try installing the infinality complete font package by bohoomil. I will further post on my progress.

You made a big progress. On Win10_64, source window put chars normally.
I have finished install CentOS and Quartus Lite 16. vsim console said vsim need 32bit lib install.
It seems the problem is same on ARCH. So I come to think I don't need to try the near platform CentOS. CentOS's repo
has very few(pretty poor). I wonder which dist linux have rich repo.
Anyway I will investigate the problem from your hints. I think the problem might be among C and tcl.
I didn't idetify where, but I saw the negative signs in the 'strace output' of vsim on Ubu...
However I don't think strace might not be effective tool to see inside the quartus and modelsim.
I would like to know what tools do you use.
