Filename restrictions in Google Drive?

[icrew]

Hi all:

I feel like I should be able to find this in about 10 seconds, but my search mojo is completely failing me. Can anyone point me to the reference for the characters that are/are not valid in a Google Drive filename? I'd expect that I might be able to find it on https://developers.google.com/drive/api/v3/reference/files, but no luck there. (For example, I'm wondering if there's a chance that there might be something screwy like a newline character in a Drive filename...)

Pointers most appreciated!

Thanks,

Ian
