When loading a bdf or a pcf font, specifically unifont in my case, the width of characters is incorrect.
To reproduce:
Change the extension to .bdf
Install the font. In my case, I needed to copy it to ~/.local/share/fonts/misc/
Run fc-cache -fv in the terminal.
Start emacs.
From the menu bar, choose options -> select default font.
Search for and choose Unifont Sans Serif size 12 (size should go to 12 anyways).
The unexpected result is that each character is rendered with a full width, as if there is a space after it. The cursor becomes square instead of a half-width rectangle.
Additionally, note that this does NOT occur with the ttf version of unifont. Nor does this bug occur when I use the bdf unifont inside the gnome terminal.
