Its a reference to UnicodeDecodeError while using cyryllic .I have same problem with Python 3.3 and Pycharm 2.7.2 Tryed to hardcode encoding in code, manually specifying encoding in Pycharm options, but no effect. It still tries to open utf-8 file with cp1251 lib.

Connected to pydev debugger (build 129.314)
Traceback (most recent call last):File "C:\Program Files (x86)\JetBrains\PyCharm 2.7.2\helpers\pydev\pydevd.py", line 1481, in <module>debugger.run(setup['file'], None, None)File "C:\Program Files (x86)\JetBrains\PyCharm 2.7.2\helpers\pydev\pydevd.py", line 1124, in runpydev_imports.execfile(file, globals, locals) #execute the scriptFile "C:\Program Files (x86)\JetBrains\PyCharm 2.7.2\helpers\pydev\_pydev_execfile.py", line 33, in execfile

return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x98 in position 2839: character maps to <undefined>

In debug tracker http://youtrack.jetbrains.com/issue/PY-3669 this problem marked as solved, but its still here.

Any suggestions ?

The sample code from that ticket worked fine for me with Python 3.3 and PyCharm 2.7.3 (2 lines:

 # -*- coding: utf-8 -*-print("януари")

).

Does it work for you?

Do you use remote debugger?

There is another one open bug that could be related: http://youtrack.jetbrains.com/issue/PY-10241
