I have a socket server that is supposed to receive UTF-8 valid characters from clients.
The problem is some clients (mainly hackers) are sending all the wrong kind of data over it.
I can easily distinguish the genuine client, but I am logging to files all the data sent so I can analyze it later.
Sometimes I get characters like this
œ that cause the
I need to be able to make the string UTF-8 with or without those characters.
For my particular case the socket service was an MTA and thus I only expect to receive ASCII commands such as:
EHLO example.com MAIL FROM: <email@example.com> ...
I was logging all of this in JSON.
Then some folks out there without good intentions decided to sell all kind of junk.
That is why for my specific case it is perfectly OK to strip the non ASCII characters.
str = unicode(str, errors='replace')
str = unicode(str, errors='ignore')
Note: This will strip out (ignore) the characters in question returning the string without them.
For me this is ideal case since I'm using it as protection against non-ASCII input which is not allowed by my application.
Alternatively: Use the open method from the
codecs module to read in the file:
import codecs with codecs.open(file_name, 'r', encoding='utf-8', errors='ignore') as fdata:
Changing the engine from C to Python did the trick for me.
Engine is C:
pd.read_csv(gdp_path, sep='\t', engine='c')
'utf-8' codec can't decode byte 0x92 in position 18: invalid start byte
Engine is Python:
pd.read_csv(gdp_path, sep='\t', engine='python')
No errors for me.
