Right; it is an NM issue.  If NM crashes or misbehaves with a weird
SSID, we need to fix it.

As specified in the 802.11 standard, the ESSID is a 32-byte byte array,
there are no restrictions made as to what content that 32-bytes may
contain.  It is up to the program to attempt to coerce that value into
something to present to the user.
