These Nerdfonts codepoints were removed in [3.0.0](https://www.nerdfonts.com/releases#v3.0.0):
> **Breaking 2: Material Design Icons Codepoints**
>
> The old Material Design Icon codepoints are finally dropped. Due to an historic mistake we placed them in between some asiatic glyphs, breaking that script. Since v2.3.0 the (updated and expanded) Material Design Icons have new codepoints in the 5 digit region.
>
> - Dropped codepoints `F500`… and class names `nf-mdi-*`
> - New codepoints `F0001`… and class names `nf-md-*`
> - The whole discussions are here: https://github.com/ryanoasis/nerd-fonts/issues/365
> - A translation table is available here: https://github.com/ryanoasis/nerd-fonts/issues/1059#issuecomment-1404891287
> - There are tools out there that probably can update your configuration.
For the majority of the removed symbols, it was as easy as finding the
replacement with the exact same name. For example, `f76b` (`nf-mdi-format_header_2`)
became `f026c` (`nf-md-format_header_2`).
There was one symbol that was completely removed (it was removed from
Material Design): `f5fc` (`nf-mdi-camcorder_box`). I have substituted it
with `f03d` (`nf-fa-video_camera`) which is not Material Design, but the
closest icon I could find.
Here's some example output from [nerdfix](https://github.com/loichyan/nerdfix)

We introduce a module in charge to display and toggle on click the
power profiles via power-profiles-daemon.
https://gitlab.freedesktop.org/upower/power-profiles-daemon
This daemon is pretty widespread. It's the component used by Gnome and
KDE to manage the power profiles. The power management daemon is a
pretty important software component for laptops and other
battery-powered devices.
We're using the daemon DBus interface to:
- Fetch the available power profiles.
- Track the active power profile.
- Change the active power profile.
The original author recently gave up maintenance on the project. The
Upower group took over the maintenance burden… …and created a new
DBus name for the project. The old name is still advertised for now.
We use the old name for compatibility sake: most distributions did not
release 0.20, which introduces this new DBus name. We'll likely revisit
this in the future and point to the new bus name. See the inline
comment for more details.
Given how widespread this daemon is, I activated the module in the
default configuration.
