I'm trying to work with the JSON output taken from an sqlcipher output (taken from here)
sqlcipher/sqlcipher -json -noheader "db.sqlite" "PRAGMA key = \"x'"MY-ENCRYPTION-KEY"'\";PRAGMA encoding = \"UTF-8\";select * from messages_fts_data;" > messages_fts_data.json
but when I try to load the content with a Python3 script I'm getting problems with the encoding:
>>> json.load(open("messages_fts_data.json"))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python3.7/json/__init__.py", line 293, in load
return loads(fp.read(),
File "/usr/lib64/python3.7/codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x81 in position 32: invalid start byte
(I'm cheating a bit here - in my 'real' code I'm stripping of b'[{"ok":"ok"}]\n' first but since I'm getting the error when reading the file it's definitely not just an JSON error)
When I try to handle the encoding manually by specifying encoding="utf-8" in the load() or open() commands, I'm getting the same error.
What am I doing wrong? I thought I told sqlcipher to generate UTF-8 encoded output but this seems to not work.

I am trying to use symspell in python to spellcheck some old spanish texts. Since they are all texts I need a dictionary that has old spanish words so I downloaded the large dictionary they share here which is a msgpack.
According to the basic usage, I can load a dictionary using this code
sym_spell = SymSpell(max_dictionary_edit_distance=2, prefix_length=7)
dictionary = pkg_resources.resource_filename(
"symspellpy", "dictionary.txt"
)
sym_spell.load_dictionary(dictionary, term_index=0, count_index=1)
as shown here
But when I try it with the msgpack file like this
sym_spell = SymSpell(max_dictionary_edit_distance=2, prefix_length=7)
dictionary = pkg_resources.resource_filename(
"symspellpy", "large_es.msgpack"
)
sym_spell.load_dictionary(dictionary, term_index=0, count_index=1)
I get this error
Traceback (most recent call last):
File ".../utils/quality_check.py", line 24, in <module>
sym_spell.load_dictionary(dictionary_path, term_index=0, count_index=1)

(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xdc in position 0: invalid continuation byte
I know this means the file is supposed to be a txt file but anyone has an idea how I can load a frequency dictionary stored in a msgpack file with symspell on python?
I'm using a program that reads data from a ubertooth-one device. I put the input data into a pipe file (made with mkfifo), but when i try to read the data i have the following error:
Exception in thread Thread-2:
Traceback (most recent call last):
File "/usr/lib/python3.9/threading.py", line 973, in _bootstrap_inner

(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb2 in position 2: invalid start byte
My code is this one:
# with FIFO as : '/tmp/pipe'
def interpretar():
with open(FIFO) as fifo:
while True:
print ("{}".format(fifo.readline()))
The command excecuted is ubertooth-rx -q /tmp/pipe
following the documentation:
• -q <file.pcap> : Capture packets to PCAP
The data you are getting is not unicode/text so can't be decoded as such. Try open(FIFO, "rb") to open in binary mode and read (instead of readline) to read binary data.
When I am trying to read a csv file I am getting this type of error:
Traceback (most recent call last):
File "/root/Downloads/csvafa.py", line 4, in <module>
for i in a:
File "/usr/lib/python3.8/codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte
The code that i used:
import csv
with open('Book1.csv') as f:
a=csv.reader(f)
for i in a:
print(i)
i even tried to change the encoding to latin1:
import csv
with open('Book1.csv',encoding='latin1') as f:
a=csv.reader(f)
for i in a:
print(i)
After that i am getting this type of error message:
Traceback (most recent call last):
File "/root/Downloads/csvafa.py", line 4, in <module>
for i in a:
_csv.Error: line contains NUL
I am a beginner to python
This error is raised when we try to encode an invalid string. When Unicode string can’t be represented in this encoding (UTF-8), python raises a UnicodeEncodeError. You can try encoding: 'latin-1' or 'iso-8859-1'.
import pandas as pd
dataset = pd.read_csv('Book1.csv', encoding='ISO-8859–1')
It can also be that the data is compressed. Have a look at this answer.
I would try reading the file in utf-8 enconding
another solution might be this answer
It's still most likely gzipped data. gzip's magic number is 0x1f 0x8b, which is consistent with the UnicodeDecodeError you get.
You could try decompressing the data on the fly:
with open('destinations.csv', 'rb') as fd:
gzip_fd = gzip.GzipFile(fileobj=fd)
destinations = pd.read_csv(gzip_fd)

f = open('gtp.pcap')

What is this error when i try to parse a simple pcap file?
I am running this simple pcap parser code. But it is showing the above
error. Can anyone please help.
Can you please check this link.

according to the answer suggestion, UTF-8 encounters an invalid byte which it cannot decode. So if you just read your file in binary format this error will not come as the decoding will not happen and the file contents will remain a bytes.
Open the file in binary mode
f = open('gtp.pcap', 'rb')
pcap = dpkt.pcap.Reader(f)

I am trying to convert large binary file contains Arabic words with 300 dimension vectors into pickle dictionary
What I am write so far is:
import pickle
ArabicDict = {}
with open('cc.ar.300.bin', encoding='utf-8') as lex:
for token in lex:
for line in lex.readlines():
data = line.split()
ArabicDict[data[0]] = float(data[1])
pickle.dump(ArabicDict,open("ArabicDictionary.p","wb"))
The error which I am getting is:
Traceback (most recent call last):
File "E:\Dataset", line 4, in <module>

File "E:\lib\codecs.py", line 321, in decode
