utf-8 surrogates not allowed error on heyoo library loading

[Laknos]

hello.

I'd like to report an error that prevents me from loading the library on some machines but not in others, also i experienced this error upon loading the library on Heroku:
UnicodeEncodeError: 'utf-8' codec can't encode characters in position 172-173: surrogates not allowed.

after toying with the library code i found a make do solution: removing the two instances of '\uD83D\uDE00' and the single instance of (😀) in the send_reaction function documentation.

I also had that issue. Converting the docstring to a raw string fixes it.
