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)

The example configuration in the man page used 'headphones' and 'handsfree' as keys for format-icons. The correct keys are 'headphone' and 'hands-free'.
This Patch allows the stretching of modules-{left,center,right} as well
add a "expand" flag to AModule. This allows one module to consume the
leftover space.
To allow the left or right modules to fully consume the center, the
changes also include a way to remove the center box (center_)
altogether.
