I have installed SageMath 8.0 on Windows 10 as the following instruction.

wiki.sagemath.org/SageWindows

Everything ᅟ seemed to work well first, but I got an error message as follows.

sage: 1+1
2
sage: plot(sin(x))

/opt/sagemath-8.0/local/lib/python2.7/site-packages/sage/repl/rich_output/display_manager.py:590: RichReprWarning: Exception in _rich_repr_ while displaying object: 'ascii' codec can't decode byte 0xea in position 6: ordinal not in range(128)
  RichReprWarning,  Graphics object consisting of 1 graphics primitive
sage:

Does anybody know a solution for this problem?

Is it possible the user's username contains non-ASCII characters? If so, I don't think this a problem specific to Windows.

Or perhaps, more precisely, on your machine, in the Sage prompt what does from sage.env import SAGE_TMP; SAGE_TMP output?

To Iguananaut, thanks for comments. You are right. The username of windows account contains non-ascii character, which is very common situation in Windows Korean distribution. I wil try to use new account of ascii acaracter.

And, here is the output from your command;

sage: from sage.env import SAGE_TMP; SAGE_TMP
---------------------------------------------------------------------------
