If the link will not work for u..then

The following six characters are not allowed: ?, ", $, [, \, ],
and +. In addition, the following three characters cannot be the first
character: !, #, and ;.

Well I found out, the hard way, that one of my devices doesn't accept a \. It does accept all the other non-allowed characters though.

Oh wait that was in the passphrase not the SSID.

I did some checking and apparently the IEEE 802.11 standard doesn't say anything about prohibited characters. Cisco doesn't allow the ones you quote but other vendors do

I also found that although SSID's can be 32 chars long some devices only allow 31 (31 plus nul terminator makes 32 total).

Go figure..well only looked into it because was thinking when I get back home...will transmit a SSID like "See Bob for a Good time" with the email addy on a spare router not hooked to the net.
