How to solve the problem that Korean is not recognized in csv file?

Hello. I am a Korean developer.

I am trying to apply D3 CHART called Radial Stacked Bar Chart, but a problem occurs because the CSV file does not recognize Korean.

Is there any way to apply the encoding=UTF-8 option when recognizing CSV files? The original code is this.(Radial Stacked Bar Chart / D3 / Observable)

Can you please create and link-share an example notebook that demonstrates the problem?
