Zombie Pigmen unable to be detected by command blocks using their names

I was using command blocks, and I was trying to detect the name for the default zombie pigman. However, with the names changed in 1.11, this adds a space in between the two words. Due to the fact entities cannot be detected by names with spaces in them, this renders them completely unable to be detected with names. This may be visually unpleasing to see in game, "BlueEnderKid was slain by ZombiePigman" but I'm hoping you take this into consideration, and change it so it can detect the default name, ZombiePigman, for example.
Thanks for reading, and hopefully you'll take this into consideration.
