Hi. You are using a slightly inaccurate terminology.
``tty`` is a kernel subsystem that supports terminals. Terminal could be * hardware device connected to the serial port, * virtual terminal -- so-called vty that runs on top of virtual console which is emulated by kernel using your videocard and keyboard, * pseudo terminal backed by user-mode software (like xterm or sshd server) I assume you are speaking about a "virtual terminal" that runs on console (either in text mode or in graphics mode using framebuffer). Fonts are usually installed in ``/usr/share/consolefonts/`` You can install one with ``setfont(8)``. Debian provides a package named ``console-setup`` that handles that. Run ``dpkg-reconfigure console-setup`` to configure and read ``console-setup(5)`` Useful links: https://tldp.org/LDP/LG/issue91/loozzr.html https://www.linusakesson.net/programming/tty/
