"I don't want to install a Nerdfont"

If you do not want a crispy looking tree, you can include the --mute-icons flag to disable icons.

Including this flag every time you run nomad can become cumbersome, so it may be helpful to create an alias for it in your .bashrc or equivalent:

# In `.bashrc`

alias nd="nd --mute-icons"

Also, you are lame as fuck.
