Since the update that specifies "home worlds", almost any macro command that can be executed with PC names does not work when using the PC name.
Player named "Player Name"
entering the command /invite "Player Name" returns "Player Name” is not a valid PC name.
Specifying their home world as it's done in whisper - /invite "Player Name@World" or "Player Name"@World returns the same error.

Various commands such as /trade "Player Name", /meldrequest "Player Name" etc. cannot be executed without targeting or clicking the intended PC.
