Up to at least PowerShell 7.1, passing arguments with embedded " characters to external programs such as 7z.exe is fundamentally broken, unfortunately.

While there are workarounds, the simpler solution is to provide the password via stdin.

The post that Mark Tolonen links to shows this technique for cmd.exe, via <, its input-redirection operator, which PowerShell does not support, however.

Instead, use PowerShell's pipeline to supply data that an external program receives via stdin.

Assuming that the verbatim password is ".":

'"."' | & "C:\Program Files (x86)\7-Zip\7z.exe" t test.rar
