Sympy live shell is giving UnicodeEncodeError

[guu1227]

This is occurring for me every time I try to run anything in sympy live, looks like a case of needing to use .encode for encoding unicode:
>>> str(Integral(sqrt(1/x), x)) Exception in SymPy Live of type <type 'exceptions.UnicodeEncodeError'> for reference the last 5 stack trace entries are Traceback (most recent call last): File "/base/data/home/apps/s~sympy-live-hrd/66.426491309333028408/app/handlers.py", line 271, in post live.evaluate(statement, session, printer, stream) File "/base/data/home/apps/s~sympy-live-hrd/66.426491309333028408/app/shell.py", line 280, in evaluate exec code in statement_module.__dict__ File "<string>", line 1, in <module> File "/base/data/home/apps/s~sympy-live-hrd/66.426491309333028408/sympy/sympy/printing/pretty/pretty.py", line 2665, in pretty_print imaginary_unit=imaginary_unit)) File "/base/alloc/tmpfs/dynamic_runtimes/python27g/3f4b27f16594164f/python27/python27_lib/versions/1/google/appengine/runtime/request_environment.py", line 104, in write self._request.errors.write(data) UnicodeEncodeError: 'ascii' codec can't encode character u'\u2320' in position 0: ordinal not in range(128)

Traceback reformatted for readability:

>>> str(Integral(sqrt(1/x), x))

I'm not able to reproduce. I tried with both LaTeX and Unicode Output Formats:

Possibly something earlier the session broke, but Integral(sqrt(1/x), x) in isolation seems to work:

@guu1227 could you please try opening this link in an incognito/private browser to test:
https://live.sympy.org/?evaluate=Integral(sqrt(1%2Fx)%2C%20x)%0A%23--%0Astr(Integral(sqrt(1%2Fx)%2C%20x))%0A%23--%0A

Sorry I missed this comment
I'm not getting the trace with either a private browser or a normal browser on the linked page. It only seems to be occurring when I try to use the pop up live shell on the sympy tutorial web page.
Also, it doesn't happen when I open the tutorial page in a private browser. The trace does appear if I try to run any command on the tutorial page's sympy live shell using a normal browser, though.
