2016-02-09 15:54:46 +0200	asked a question	error when perform symbolic calculation in Octave of Sage I have tried the Octave (matlab-like) kernel in Sagemathcloud, but when I intended to perform the symbolic calculation in Octave, something strange happened, and I can't solve it. My code is as follows: `pkg load symbolic syms x f = sin(x)^2; diff(f)` when I execute it, error happened, it said 'ascii' codec can't encode character u'\u22c5' in position 13: ordinal not in range(128) How can I solve this problem?
