why is [Content] encoded and how to solve it?

[jJayyyyyyy]

Description

After making a comment with markdown syntax, all the data were sent to my GitHub repo. But the question is, they've been encoded.

What I write in comment zone is:

markdown test

```python
print("hello world")
```

but on GitHub Pull Request, it's some kind of encoded, and could not be rendered properly by markdownify filter

markdown test

```python
print('hello world')
```

I've googled it but nothing works. Could you please tell me how to solve it and to properly render the markdown syntax? Thanks a lot!

PS: Comm(ent|it) is really awesome!
