My money is on file encoding, can you check what encoding the file is using?

All,

I'm getting an error trying to run a simple scan with Nmap, as shown.
Running in a CMD session on Win10 20H2. Scans with Zenmap work when not
using a file, as does Nmap. It's just when trying to use a file that I get
this very strange output. I've upgraded npcap from 1.10 to 1.31, and get
the same behavior out of both.

Am I doing something ignorant/stupid, or have I stumbled upon a bug?
Further information gladly provided.
