This post is a wiki. Anyone with karma >750 is welcome to improve it.

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?

If you don't have to use Jupyter, you can create a Sage worksheet (file ending in .sagews), then put %octave at the top of a cell, and your example works. For example: https://cloud.sagemath.com/projects/4...
I've reported your bug to the Octave jupyter kernel issue tracker: https://github.com/Calysto/octave_ker...
