Subject: bug#35079: 26.1; Font rendering - problem with bdf fonts
Date: Tue, 2 Apr 2019 01:31:09 -0400 [thread overview]
Message-ID: <CAAKArVHNwCtVP_kPzCc74AhTwRG89DqiSj5=p0C43ff8JGfOYw@mail.gmail.com> (raw)

When loading a bdf or a pcf font, specifically unifont in my case, the
width of characters is incorrect.
To reproduce:
Download the bdf.gz file from the unifont website at
http://unifoundry.com/unifont/index.html
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.
