Scrapy Exporting Weird Symbols Into Csv File
Ok, so here's the issue. I'm a beginner who has just started to delve into scrapy/python. I use the code below to scrape a website and save the results into a csv. When I look in
Solution 1:
Officiële will be represented as u'Offici\xeble' in Python 2, as seen in the python shell session example below (no need to worry about the \xXX characters, it's just how Python represents non-ASCII Unicode characters)
$ python
Python 2.7.9 (default, Apr 22015, 15:33:21)
[GCC 4.9.2] on linux2
Type"help", "copyright", "credits"or"license"for more information.
>>> u'Officiële'u'Offici\xeble'>>> u'Offici\u00EBle'u'Offici\xeble'>>> I think this is because it's saving in unicode instead of UTF-8
UTF-8 is an encoding, Unicode is not.
ë, a.k.a U+00EB, a.k.a LATIN SMALL LETTER E WITH DIAERESIS, will be UTF-8 encoded as 2 bytes, \xc3 and \xab
>>>u'Officiële'.encode('UTF-8')
'Offici\xc3\xable'
>>>In the csv file, it changes it to officiële.
If you see this, it's probably that you need to set the input encoding to UTF-8 when opening the CSV file inside your program.
Scrapy CSV exporter will write Python Unicode strings as UTF-8 encoded strings in the output file.
Scrapy selectors will output Unicode strings:

Let's see what a spider extracting these strings in items will get you as CSV:
$ cat testspider.py
import scrapy
classTestSpider(scrapy.Spider):
name = 'testspider'
start_urls = ['https://zoek.officielebekendmakingen.nl/zoeken/resultaat/?zkt=Uitgebreid&pst=Tractatenblad|Staatsblad|Staatscourant|BladGemeenschappelijkeRegeling|ParlementaireDocumenten&vrt=Cybersecurity&zkd=InDeGeheleText&dpr=Alle&sdt=general_informationPublicatie&ap=&pnr=18&rpp=10&_page=1&sorttype=1&sortorder=4']
defparse(self, response):
for t in response.css('div.menu-bmslink > ul > li > a::text').extract():
yield {"link": t}
Run the spider and ask for CSV output:

You can verify that ë is correctly encoded as c3 ab
I can see the file data correctly when using LibreOffice for example (notice "Character set: Unicode UTF-8"):
You are probably using Latin-1. Here's what you get when using Latin-1 instead of UTF-8 as input encoding setting (in LibreOffice again):
Solution 2:
To encode a string you can directly use encode("utf-8") . Something like this:
item['publicatiedatum'] =''.join(sel.xpath('//span[contains(@property, "http://purl.org/dc/terms/available")]/text()').extract()).encode("utf-8")
