Pasted code shifted and unusable

I have a large script that I am wanting to use to create a file on a server that I am SSH'd into. I am SSH'd into a Server 2019 system running

PS > sshd -V
OpenSSH_for_Windows_9.5p2, LibreSSL 3.8.2

I have SSH'ing to this system from an Ubuntu WSL system, from a Windows CMD shell, and from a PowerShell v5 shell. The results are all the same. My code is seriously shifted beyond repair

When I paste the same code into VS Code everything is fine

additionally, when I start a new file when SSH'd in from the Ubuntu WSL system I get the strange characters at the top of the file (I thought this was fixed)

The strange characters at the top of the file does not happen when I open / start a new file when SSH'ing from the Windows CMD or Widnows PowerShell shells.

Edit is at the current version - v 1.2.1

Reproduce the issue in Edit v1.2.1 over SSH from Ubuntu WSL, Windows CMD, and PowerShell using the large pasted script described here. Compare the resulting alignment and file headers with local VS Code and determine whether the terminal input or file creation path causes the difference. Done means pasted code remains usable and the unexpected characters do not appear in the affected environment.
