These .desktop files however assume the application is in $PATH, since the commands in the files to not include an absolute path to the binaries.
There is also an instruction on which commands to run when, in .../scilab-5.5.2/share/applications.
Of course i tried installing with both official website and brew (brew had no success, it only installs scilab 6.1.1), then I thought the .exe windows version should work with my good old friend Wine. But what a surprise, Wine isn't compatible with newest OS (fcking 32-bit incompatibility) !
My university requires me to use this software called Scilab. It uses Java. The last time, there was some GTK-look-and-feel problem. I was able to fix that. Then after working fine for months, one day I discover that (again) all fonts disappeared. Only console text is seen, but all text from menus etc vanished. In scilab settings, I was able to somehow (half-blindly) change the font, but nothing works.
Sorry but I can't know how to fix your font problems from your description. However, one suggestion for your old thread is that, you can install a aur package manager like yay (manually from aur), and use yay -S scilab, it will install all dependencies from aur automatically. I think that a package from aur may function better.
By the way, if you can run scilab from a terminal, you may see the feedback from scilab, which probably contain errors and warnings. Examine and post them, or search for them on the web. You will get more answer.
Who told you this and why? First try the AUR scilab-bin version, since it's the binary version 6.1.0 from upstream with some patches and it has recent comments/suggestion in the Comments section that seem to suggest it should work. You'll need one additional AUR dependency (ncurses5-compat-libs), but other than that there's little or no deps.
