What is failing
I'm trying to SCP a file which contains a space:

scp -o BatchMode=yes -o ConnectTimeout=3 -o StrictHostKeyChecking=no administrator@10.0.0.10:'"C:/ProgramData/AA Care/Enterprise Archive 4.0/Error_20180226.log"' /tmp/check_logfiles_remote.17955

Expected output
File is copied

Actual output
protocol error: filename does not match request

I've tried various combinations of quotes and backslashes, this is the closest I've managed to get but I'm now getting a protocol error

I'm connecting using a key, SSH is set to use PowerShell

Research direction

Reproduce the SCP command against the Windows Server 2012 R2 host, using the quoted path with spaces and PowerShell as the SSH shell. Start by tracing SCP filename handling on the Windows server and compare the requested path with the filename returned to the Ubuntu client. Done means the file copies successfully without a protocol error.
