As mentioned a few months ago: an SSID is specified in 802.11 as octets.
As also menitoned before: Most SSIDs I've come across do tend to contain
ASCII characters for most if not all octets.

In this specific instance, I consider '.' to be the better solution - as
it makes traces easier for me to read in a vast majority of cases.
Whether this should be changed in all places: I don't know. The only
other place where I ever noticed this as maybe a bit unreadable are the
"radius passwords". I think the people using these dissectors
should decide this on a case by case basis.
Also mentioned before: The display as ASCII is just a convenient thing
for most people living in areas where a latin alphabet is used. In
other areas of the world - this display will be worthless. Maybe if
soneone feels like it, an option to interpret octet fields as ascii,
latin1, utf-8 ..... could be added to the general preferences. Until
such a time, I'd be happy to have the interpretation as ASCII back :-)

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
