ERROR - Error reading page 'xxxx/xxx.ipynb': Unicode strings with encoding declaration are not supported. Please use bytes input or XML fragments without declaration.

its related to lxml

File "src/lxml/etree.pyx", line 3254, in lxml.etree.fromstring

workaround: put # coding: utf-8 in the notebook

I believe it is not related to package, closing the issue

I ran into this issue as well.

@tonylee2016 can you please clarify where you think this error is originating from? Is it nbconvert or lxml? I haven't found issues in any other projects that seem to be related to this.

its nbconvert, I think it calls lxml. In my case, one cell in my notebook is using schemdraw. After I clear the output in that cell, it worked.

Looks like there was a partial fix here: jupyter/nbconvert#1837
And finishing that is tracked here: jupyter/nbconvert#1849

I get this error when I try to run the demo. It occurs in the ruby.ipynb notebook. Removing it allows the demo to run.
