netconnectd does not recognize all valid wireless SSID values

[crawlingChaos]

A wireless SSID can be any set of octets of length from 1 to 32. There is no restriction limiting a SSID to printable characters.

I have functioning wireless networks with names that consist only of varying numbers of space characters. wpa_supplicant has no problem with them yet netconnectd does. Presumably because it parses the SSID as a string?

Or because it relies on /etc/network/interfaces and the wifi library to perform wifi configuration. Have you ever created a working client connection to one of those no-printable-character-SSIDs via /etc/network/interfaces instead of wpa-supplicant? If so, it might be possible to patch things up (I have admit though that I haven't had time to look into netconnectd for ages now since at the moment I don't use it myself).
