Certain keys on the keyboard for symbols (the ";" key is the best example of this), do not display the correct symbol when typed into chat.
Although there's no physical way I can display proof of this bug, I'll merely give you directions on how to do it.
Start a Co-Op game (using your house's PC or in a Pokémon Center), then type whatever key that opens the chat box (it's rebindable). Attempt to type symbolic keys on a keyboard; some do not input the correct symbols.
