I have the Oh-my-posh prompt installed for the PowerShell terminal and
runs just fine in the Windows terminal and Alacritty, but when I try
to open PowerShell from within Emacs, I see “?” symbols all over the
prompt.

This is my configuration for PowerShell:

    (defun run-powershell ()
      "Run powershell"
      (interactive)
      (async-shell-command "C:/Program Files/PowerShell/7/pwsh.exe"
                           nil
                           nil))

    (defun my-buffer-face-mode-fixed ()
       "Sets a fixed width (monospace) font in current buffer"
       (interactive)
       (setq buffer-face-mode-face '(:family "FuraCode NF" :height
100))
       (buffer-face-mode))
    (add-hook 'shell-mode-hook 'my-buffer-face-mode-fixed)

1. Is that a typo? Never heard of FuraCode, but FiraCode is definitely
a font.

2. https://github.com/jschaf/powershell.el exists. M-x powershell,
plus syntax highlighting files.

I have tried to use `powershell.el`, but I am getting this error:

    $pswidth; if ($cwidth -lt $pswidth) { $rawui.BufferSize =
$bufsize; $rawui.WindowSize = $winsize; } elseif ($cwidth -gt
$pswidth) { $rawui.WindowSize = $winsize; $rawui.BufferSize =
$bufsize; }; Set-Variable -name rawui -value $null; Set-Variable -name
winsize -value $null; Set-Variable -name bufsize -value $null; Set-
Variable -name cwidth -value $null; }

And then on another line I am getting

    SetValueInvocationException: Exception setting "BufferSize":
"Cannot set the buffer size because the size specified is too large or
too small. (Parameter 'value')
Actual value was 7,9001.

You need to set the correct font for Emacs, that's all.
