I'm having problems reading from a file, processing its string and saving to an UTF-8 File.
Here is the code:
try:
filehandle = open(filename,"r")
except:
print("Could not open file " + filename)
quit()
text = filehandle.read()
filehandle.close()
I then do some processing on the variable text.
And then
try:
writer = open(output,"w")
except:
print("Could not open file " + output)
quit()
#data = text.decode("iso 8859-15")
#writer.write(data.encode("UTF-8"))
writer.write(text)
writer.close()
This output the file perfectly but it does so in iso 8859-15 according to my editor. Since the same editor recognizes the input file (in the variable filename) as UTF-8 I don't know why this happened. As far as my reasearch has shown the commented lines should solve the problem. However when I use those lines the resulting file has gibberish in special character mainly, words with tilde as the text is in spanish. I would really appreciate any help as I am stumped....
Process text to and from Unicode at the I/O boundaries of your program using open
with the encoding
parameter. Make sure to use the (hopefully documented) encoding of the file being read. The default encoding varies by OS (specifically, locale.getpreferredencoding(False)
is the encoding used), so I recommend always explicitly using the encoding
parameter for portability and clarity (Python 3 syntax below):
with open(filename, 'r', encoding='utf8') as f:
text = f.read()
# process Unicode text
with open(filename, 'w', encoding='utf8') as f:
f.write(text)
If still using Python 2 or for Python 2/3 compatibility, the io
module implements open
with the same semantics as Python 3's open
and exists in both versions:
import io
with io.open(filename, 'r', encoding='utf8') as f:
text = f.read()
# process Unicode text
with io.open(filename, 'w', encoding='utf8') as f:
f.write(text)
You can also get through it by the code below:
file=open(completefilepath,'r',encoding='utf8',errors="ignore")
file.read()
You can't do that using open. use codecs.
when you are opening a file in python using the open built-in function you will always read/write the file in ascii. To write it in utf-8 try this:
import codecs
file = codecs.open('data.txt','w','utf-8')
The encoding parameter is what does the trick.
my_list = ['1', '2', '3', '4']
with open('test.txt', 'w', encoding='utf8') as file:
for i in my_list:
file.write(i + '\n')
Success story sharing
errors=ignore
orerrors=replace
toopen()
... if you do not know the file's encoding. :)io.open
expects Unicode strings to be written, not byte strings. It does the encoding to the declared encoding.ascii
codec, so it will work as long as the string is only ASCII. That's why Python 3 changed it...it prevents "it will work sometimes" which is an annoying bug to track down.
