I order to download a font with a space in the name, I had to quote the name with both double and single quotes.

# Works as expected.
google-font-download "'Open Sans'"

This is in contrast with the docs which use Open Sans as an example, and only one set of quotes. Looking at the command output, it looks like the space will be parsed as two fonts, Open and Sans.

# Doesn't work as expected.
google-font-download "Open Sans"
