I know people easily make money off of wc3 but really trying to make money by ripping ppl off with simple triggers and telling them to pay. . .?
The second thing isn't possible unless you have a customized wc3 or played a game and left it that had those values edited.
Here's a way of doing it and how almost exactly they likely did it.
[trigger=example]
Events
Map initialization
Conditions
(Name of Player 1 (Red)) Equal to Dat-C3
Actions
Player - Set name of Player 1 (Red) to (® + (Name of Player 1 (Red)))
[/trigger]
The alt code for the copyright symbol is alt 0174

Another way is this and its the better way.
[trigger=example]
Events
Map initialization
Conditions
Actions
Player Group - Pick every player in (All players) and do (Actions)
Loop - Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(Name of (Picked player)) Equal to Dat-C3
Then - Actions
Player - Set name of (Picked player) to ((Name of (Picked player)) + ®)
Else - Actions
