.html some advice if you are making or saving this these files,then there is a way if using Requests and BS to always save as utf-8.If files are already made then as bye Gribouillis there is chardet.
So eg if i have one .html file which(i make to be latin-1) and one in utf-8.
λ chardetect page_latin.html page_latin.html: ISO-8859-1 with confidence 0.73 G:\div_code\html_utf λ chardetect page_utf8.html page_utf8.html: utf-8 with confidence 0.7525
from bs4 import BeautifulSoup
with open('page_latin.html', encoding='latin-1') as fp:
soup = BeautifulSoup(fp, 'lxml')
h1_tag = soup.find('h1')
print(h1_tag)
# Utf-8 the default
with open('html_new.html') as fp:
soup = BeautifulSoup(fp, 'lxml')
h1_tag = soup.find('h1')
print(h1_tag)Output:<h1>Jalapeñod je pèle</h1>
<h1>Jalapeñod je pèle</h1>encoding='latin-1' it break and get UnicodeDecodeError.Can also convert to utf-8 as this happens when open a file in Beautiful Soup:
Bs4 Doc Wrote:Any HTML or XML document is written in a specific encoding like ASCII or UTF-8.
But when you load that document into Beautiful Soup, you’ll discover it’s been converted to Unicode.
Beautiful Soup uses a sub-library calledUnicode, Dammitto detect a document’s encoding andconvert it to Unicode.
So from latin-1 to utf-8.
from bs4 import BeautifulSoup
with open('page_latin.html', 'rb') as fp,open('html_new.html', 'w', encoding='utf-8') as fp_out:
file_out = fp.read()
# When open a file in BS it will be Unicode
soup = BeautifulSoup(file_out, 'lxml')
fp_out.write(soup.prettify())λ chardetect html_new.html html_new.html: utf-8 with confidence 0.7525File used in test,same just with different encoding.
