wpa_supplicant wifi setup with spces in SSID and pass?

Hi all,

I'm trying to setup a Raspberry Pi Zero W with PcP, but fail at connecting to my wifi (basically failing at step #1...)

As stated in the howto; the wpa-supplicant file doesn't play nice with spaces and special characters, but doesn't say how to go about it. What format do I need to enter the details, preferably without changing the SSIDs and passwords of the Wifi networks.

Thanks, Nelis
