"UnicodeDecodeError: 'utf8' codec can't decode error when calling matlab

[liulion]

1、【matlabCode】
function ret=testFun
a=20;
b=10;
ret=a+b;

2、【Python Code】
matlab=pymat.Matlab()
matlab.start()
func_file=u"G:/Matlab/MyMatlab/testFun.m".decode("utf-8")
res2=matlab.run_func(func_file)

3、【The errors】
Starting MATLAB on ZMQ socket tcp://127.0.0.1:53224
Send 'exit' command to kill the server
.....MATLAB started and connected!
Traceback (most recent call last):

return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xca in position 22: invalid continuation byte
MATLAB closed

4、Then I debuge the errors , I found the error is caused by
the codeing:
def decode(input, errors='strict'):
return codecs.utf_8_decode(input, errors, True) in "D:\Anaconda\Lib\encodings\utf_8.py" file

5、the reason is the input parameter of 'input' is
'{"content":{"stdout":"�������̫�ࡣ"},"result":"","stack":[],"success"'

it look like that 'stdout' paramter has error code , but how could I resolve it ? the problem has block me for almost 2 weeks, would you help me ?

PS: [the error snapshot ]

[liulion]

appending more information:
It is right when I call the function in Ipython. the snapshot as follows:

But why it is error when I call matlab in python?

PS: my environment is python2.7+matlab2013b

Hei, do you address this problem. Recently I also have encountered the same problem but do not know why

I meet the problem too. I find the error happened when matlab function return a Chinese error information. So I change the language of system from Chinese to English.
By the way, the way passing params, is use 'paramname',paramValue not use a json format.
such as
matlab.run_func('test.m','argm1',argm1Value,'argm2',argm2Value)
not
matlab.run_func('test.m',{
'argm1':argm1Value,
'argm2':argm2Value
})

})

I solve the problem by setting the language of matlab into English. I think the problem only happens when it return the result from matlab to python, and somehow the result contains some special letters/characters from other languages which causes the error mentioned above.
