Http Get a File for CSV replacing unicode characters

I’m using the Html Get a File module to pull a CSV that contains unicode characters. The extended characters are substituted for U+FFFD (diamond question mark). I’ve tried converting the encoding and toString, but can’t figure out how to preserve the characters. If I paste the contents of the CSV into a Set Variable module, it works fine. If I manually download the file, the characters are intact.


Is there a way to control the encoding on Get a File?
