RFC 2811: Internet Relay Chat: Channel management
2.1 Namespace


   Channels names are strings (beginning with a '&', '#', '+' or '!'
   character) of length up to fifty (50) characters.  Channel names are
   case insensitive.

   Apart from the the requirement that the first character being either
   '&', '#', '+' or '!' (hereafter called "channel prefix"). The only
   restriction on a channel name is that it SHALL NOT contain any spaces
   (' '), a control G (^G or ASCII 7), a comma (',' which is used as a
   list item separator by the protocol).  Also, a colon (':') is used as
   a delimiter for the channel mask.  The exact syntax of a channel name
   is defined in "IRC Server Protocol" [IRC-SERVER].

   The use of different prefixes effectively creates four (4) distinct
   namespaces for channel names.  This is important because of the
   protocol limitations regarding namespaces (in general).  See section
   6.1 (Labels) for more details on these limitations.
