error with python 3 str

[GNHua]

I am using python 3.5 to run the example code

>>> import pandoc
>>> doc = pandoc.Document()
>>> doc.markdown = '''
... # I am an H1 Tag
... 
... * bullet point
... * more points
... * point with [link](http://google.com)
... '''
>>> print(doc.rst)

There is an error because it's expecting a bytes encoded string, most likely since this library has not been updated for years. To make it work you have to set doc.markdown to the string and then append .encode('utf-8') and finally print the result by appending .decode() to doc.rst, or whatever format you want to convert to.

Here's how the example code would look with those modifications in place:

doc = pandoc.Document()

doc.markdown = '''
# I am an H1 Tag

* bullet point
* more points
* point with [link](http://kennethreitz.com)!
'''.encode('utf-8')

print(doc.rst.decode())

However, I would recommend using a more recent pandoc library if you can.
