UnicodeDecodeError utf8 codec can t decode byte 0x9c

Question

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    that cause the UnicodeDecodeError error  I need to be able to make the string UTF-8 with or without those characters   Update  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   lt john doe example com gt       I was logging all of this in JSON  Then some folks out there without good intentions decided to send all kind of junk  That is why for my specific case it is perfectly OK to strip the non ASCII characters

What can you do if you need to make a change to a file  but don   t know the file   s encoding  If you know the encoding is ASCII-compatible and only want to examine or modify the ASCII parts  you can open the file with the surrogateescape error handler   with open fname   r   encoding  ascii   errors  surrogateescape   as f      data   f read

http   docs python org howto unicode html the-unicode-type  str   unicode str  errors  replace     or  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
