csv. Reader() allows you to access CSV data using indexes and is ideal for simple CSV files. csv. DictReader() on the other hand is friendlier and easy to use, especially when working with large CSV files.

How to write Unicode characters in CSV file?

The csv module doesn’t directly support reading and writing Unicode, but it is 8-bit-clean save for some problems with ASCII NUL characters. So you can write functions or classes that handle the encoding and decoding for you as long as you avoid encodings like UTF-16 that use NULs.

Can the Python CSV module handle Unicode data by default?

Is there a way to handle UTF-8 encoding and decoding?

So you can write functions or classes that handle the encoding and decoding for you as long as you avoid encodings like UTF-16 that use NULs. UTF-8 is recommended. The example below (from the docs) shows how to create two functions that correctly read text as UTF-8 as CSV.
