Patched encom font
This is the (actual) font that is used in Tron: Legacy (so not TR2N):
The font is sourced from an archived version of http://disneydigitalbooks.go.com/tron. leveraging the waybackmachine at this url.
It has been patched such that the missing lowercase characters simply mirror the existing capital ones. This allows for easy use with applications such as polybar.
I made an AUR package for installing this font which can be installed on arch based linux distributions.
Ex. of installing with yay package manager
yay -S ttf-encom
If you are using another OS like windows, you should be able to use the builtin font manager to easily install it.
