SSH copy and complex file names (scp)

When copying a file with a somewhat complex file name (spaces, parentheses) using scp, the file name must be enclosed in quotes twice:

"'Frolovs, Oliver — Hello Gruffalo (Virgin_Tear_ Lake City Publishing 2020).pdf'"

The scp is invoked:

$ scp -i CERT.pem USER@DOMAIN:"'Horses, Obvs - Why Not (2007 _).pdf'"

This, however, might fail for some file names, resulting in a cryptic error message displayed:

protocol error: filename does not match request

Without going into much detail, the way to disable the check that results in this message, is to use -T parameter:

$ scp -T -i CERT.pem USER@DOMAIN:"'Horses, Obvs - Why Not (2007 _).pdf'"

Because, why not? Obviously.
