BUG: to_clipboard raises an error with null values in data frame

With the latest version of pandas installed on windows, running the following code will raise an error:

df = pd.DataFrame(['\x00'])
df.to_clipboard(index=False, excel=False)

Here is the traceback:

Might still be specific to different Windows OSes - see an issue like #38527 which only occurred for WSL 2.0

Hi! I use windows 10 and Python 3.8 and PyCharm professional 2020.3 . My computer uses CPU Intel core I5 9600k and 8G ram. I executed above codes and there wasn’t any error and I could print the data.
