I am trying to normalise accented characters in a string in Python 3 like this:
from bs4 import BeautifulSoup
import os
def process_markup():
#the file is utf-8 encoded
fn = os.path.join(os.path.dirname(__file__), 'src.txt') #
markup = BeautifulSoup(open(fn), from_encoding="utf-8")
for player in markup.find_all("div", class_="glossary-player"):
text = player.span.string
print(format_filename(text)) # Python console shows mangled characters not in utf-8
player.span.string.replace_with(format_filename(text))
dest = open("dest.txt", "w", encoding="utf-8")
dest.write(str(markup))
def format_filename(s):
# prepare string
s = s.strip().lower().replace(" ", "-").strip("'")
# transliterate accented characters to non-accented versions
chars_in = "àèìòùáéíóú"
chars_out = "aeiouaeiou"
no_accented_chars = str.maketrans(chars_in, chars_out)
return s.translate(no_accented_chars)
process_markup()
The input src.txt file is utf-8 encoded:
<div class="glossary-player">
<span class="gd"> Fàilte </span><span class="en"> Welcome </span>
</div>
<div class="glossary-player">
<span class="gd"> àèìòùáéíóú </span><span class="en"> aeiouaeiou </span>
</div>
The output file dest.txt looks like this:
<div class="glossary-player">
<span class="gd">fã ilte</span><span class="en"> Welcome </span>
</div>
<div class="glossary-player">
<span class="gd">ã ã¨ã¬ã²ã¹ã¡ã©ãã³ãº</span><span class="en"> aeiouaeiou </span>
</div>
and I am trying to get it to look like this:
<div class="glossary-player">
<span class="gd">failte</span><span class="en"> Welcome </span>
</div>
<div class="glossary-player">
<span class="gd">aeiouaeiou</span><span class="en"> aeiouaeiou </span>
</div>
I know there's solutions like unidecode but just wanted to find out what I'm doing wrong here.
chars.translate(no_accented_chars)
doesn't modify chars
. It returns a new string with the translation applied. If you want to use the translated string, save it to a variable (perhaps the original chars
variable):
chars = chars.translate(no_accented_chars)
or pass it directly to the write
call:
dest.write(chars.translate(no_accented_chars))
I strongly suspect that your HTML file contains something like
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
which basically forces BeautifulSoup to reinterpret the UTF-8 as ISO-8859-1 (or whichever legacy charset you have there; Windows-1252? Shudder).
There is a number of other places you can add a charset=
attribute to a block of HTML, but this would be the typical culprit.
The problem was that, as triplee suggested , the file being interpreted as the wrong encoding.
The data in the file was correct (as shown by a hex dump), but possibly due to the lack of a charset declaration Python did not read it in as utf-8, but as cp1252.
To fix this, it was necessary to explicitly state the encoding when opening the file using Python's open() method, so the line:
markup = BeautifulSoup(open(fn), from_encoding="utf-8")
needed to be changed to:
markup = BeautifulSoup(open(fn, encoding="utf-8"))
