[wjdwlgh888]

1. Operator

2. Pipeline

3. Result(Error)

4. Question

Why is there a decode error?
And what is the solution

Below is the code.
The question is simple.
How should I print out korean?
I've tried most of what Google has found, but I failed.

#code

#coding=utf-8
result = "한글 출력 테스트"
result = result.decode('utf8').encode('utf8')
api.send("outstr", result)

There might be an error with

result = "한글 출력 테스트"
result = result.decode('utf8')

as you are trying to `decode` a string, while decode is applicable to bytes.

As far as I know in Python3 all strings are already Unicode. So if I run simple

result = "한글 출력 테스트"
api.send("outstr", result)

with

I am getting a result in Wiretap
