Encoding issue while writing into csv

[abidulrmdn]

Calling a field which is

"name": {
                        "type": "keyword"
                     },

Command that i ran:
es2csv -i index -D type -f name --verify-certs -u https://userwithurl -q '*' -o database.csv

And the error that was showing was :

Traceback (most recent call last):
File "/home/ubuntu/anaconda3/bin/es2csv", line 11, in
load_entry_point('es2csv==5.2.1', 'console_scripts', 'es2csv')()

python3.5 is not supported at the moment. Please use python 2.7.

Why not just make it str instead.

@taraslayshchuk I'm using es2csv with Python 2.7 yet I'm getting this unicode-related error:

Traceback (most recent call last):
  File "/home/ubuntu/.local/bin/es2csv", line 11, in <module>
    sys.exit(main())
  File "/home/ubuntu/.local/lib/python2.7/site-packages/es2csv.py", line 284, in main
    es.write_to_csv()
  File "/home/ubuntu/.local/lib/python2.7/site-packages/es2csv.py", line 221, in write_to_csv
    csv_writer.writeheader()

    self.writerow(header)
  File "/usr/lib/python2.7/csv.py", line 152, in writerow
    return self.writer.writerow(self._dict_to_list(rowdict))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe5' in position 8: ordinal not in range(128)

So I guess using 2.x is not a solution for the problem. I'm not sure what document is problematic, but \xe5 is å.

I solved it by using unidecodecsv instead of csv:

diff --git a/es2csv.py b/es2csv.py
index b948843..509e5ea 100755
--- a/es2csv.py
+++ b/es2csv.py

@abdrmdn Answer for you question is in @katafrakt comment. More details, that's why we should use such methods.

[taraslayshchuk]

Hello @katafrakt you have definitely another error. Looks like you have unicode naming in document, to be precise it is in key name and that is not expected by this tool.

[abidulrmdn]

Since this is already resolved, I'll close the issue.

Fixed in 5.5.2.
