If you use Python 2  don t forget to add the UTF-8 file encoding comment on the first line of your script     - - coding  UTF-8 - -   This will fix some Unicode problems and make your life easier

ensure ascii False really only defers the issue to the decoding stage    gt  gt  gt  dict2     LeafTemps     xff xff xff xff     gt  gt  gt  json1   json dumps dict2  ensure ascii False   gt  gt  gt  print json1    LeafTemps            gt  gt  gt  json loads json1  Traceback  most recent call last     File   lt stdin gt    line 1  in  lt module gt    File   usr lib python2 7 json   init   py   line 328  in loads     return  default decoder decode s    File   usr lib python2 7 json decoder py   line 365  in decode     obj  end   self raw decode s  idx  w s  0  end      File   usr lib python2 7 json decoder py   line 381  in raw decode     obj  end   self scan once s  idx  UnicodeDecodeError   utf8  codec can t decode byte 0xff in position 0  invalid start byte   Ultimately you can t store raw bytes in a JSON document  so you ll want to use some means of unambiguously encoding a sequence of arbitrary bytes as an ASCII string - such as base64    gt  gt  gt  import json  gt  gt  gt  from base64 import b64encode  b64decode  gt  gt  gt  my dict     LeafTemps     xff xff xff xff      gt  gt  gt  my dict  LeafTemps     b64encode my dict  LeafTemps     gt  gt  gt  json dumps my dict     LeafTemps         w       gt  gt  gt  json loads json dumps my dict    u LeafTemps   u      w      gt  gt  gt  new dict   json loads json dumps my dict    gt  gt  gt  new dict  LeafTemps     b64decode new dict  LeafTemps     gt  gt  gt  print new dict  u LeafTemps     xff xff xff xff

If you are fine with non-printable symbols in your json  then add ensure ascii False to dumps call    gt  gt  gt  json dumps your data  ensure ascii False       If ensure ascii is false  then the return value will be a   unicode instance subject to normal Python str to unicode   coercion rules instead of being escaped to an ASCII str

One possible solution that I use is to use python3   It seems to solve many utf issues   Sorry for the late answer  but it may help people in the future   For example      usr bin env python3 import json   your code follows
