Python ASCII codec can't encode character error during write to CSV

Python 2.x CSV library is broken. You have three options. In order of complexity:

  1. Edit: See below Use the fixed library https://github.com/jdunck/python-unicodecsv (pip install unicodecsv). Use as a drop-in replacement - Example:

    with open("myfile.csv", 'rb') as my_file:    
        r = unicodecsv.DictReader(my_file, encoding='utf-8')
    

  1. Read the CSV manual regarding Unicode: https://docs.python.org/2/library/csv.html (See examples at the bottom)

  2. Manually encode each item as UTF-8:

    for cell in row.findAll('td'):
        text = cell.text.replace('[','').replace(']','')
        list_of_cells.append(text.encode("utf-8"))
    

Edit, I found python-unicodecsv is also broken when reading UTF-16. It complains about any 0x00 bytes.

Instead, use https://github.com/ryanhiebert/backports.csv, which more closely resembles Python 3 implementation and uses io module..

Install:

pip install backports.csv

Usage:

from backports import csv
import io

with io.open(filename, encoding='utf-8') as f:
    r = csv.reader(f):
