Step1:  reading
Step2:  Dialect
Step3:  Creating Dialect
<ASSISTANT_TASK:>
Python Code:
import csv
import sys
unicode_chars = 'å∫ç'
with open('data.csv', 'wt') as f:
    writer = csv.writer(f)
    writer.writerow(('Title 1', 'Title 2', 'Title 3', 'Title 4'))
    for i in range(3):
        row = (
            i + 1,
            chr(ord('a') + i),
            '08/{:02d}/07'.format(i + 1),
            unicode_chars[i],
        )
        writer.writerow(row)
print(open("data.csv", 'rt').read())
