Comment(by FelixAkk):

 I see. I that case it should indeed not blindly prefix it with a '#', to
 allow other used prefixes. Alternatively a more helpful error message
 would also clear the confusion for most cases.

 What I would suggest is checking if the entered channel name is prefixed
 with the common prefix symbol (the hash symbol). If it is not and it turns
 out the channel does not exist, display instead the following error
 message:

 "No such channel.\n Note that channel names are normally prefixed with a
 '#' (hash symbol), e.g.: #channelname"

 This would give users that assume the default prefix interpretation enough
 information about why their channel was not found.
