scrapy parse emits ANSI color sequences in the Windows terminal

Description

i try to use scrapy parse command in cmd（anaconda env），but when it logs Scraped Items and Requests, there are full of garbled code which i show you below（Additional context）. I have no idea of it, but it seems to have nothing to do with character encoding,

Steps to Reproduce

running command

>>> scrapy parse --spider=quotes3 http://quotes.toscrape.com/page/1/

the quotes3 spider shows below（Additional context）

Expected behavior: without garbled code

Actual behavior: garbled code appears

Reproduces how often: every time

Should we close this issue?

[wRAR]

Pass --nocolour. While Pygments seems to have some support for the Windows terminal, Scrapy uses TerminalFormatter which is specifically for ANSI sequences. This is probably a bug in Scrapy.
