Can't export with utf-8

[jbmg17]

I try to export in html, but in markdown cells I have text that contains "ó" or "á", so when I export to html this characters don't display well. How can export to html with utf-8 ?

Greetings.

Not sure what's going on here, but I'll check it out. Does the output look fine if you export with the stock nbconvert utility?

I've been facing the same problem. It seems that when you open a file for reading in python, without specifying the encoding, it assumes the encoding that it deems fit for the content. This means that, if I create a fresh notebook file and try to open it, it assumes UTF-8 encoding. However, if the notebook has any content with accents ("á", etc) it will assume a different encoding, in my case ANSI_X3.4-1968, making it unable to read the file, since the default encoding that python assumes is ascii.

As a "quick fix" I just patched hide_code.py to include encoding="utf-8" in any open file operations. Perhaps you would consider this to be configurable.

Example of the code with the fix:

class HideCodeHTMLExportHandler(IPythonHandler):
    def get(self, *args):
        self.log.info("hide_code: Starting HTML export for {}".format(args[-1]))
        with open(ipynb_file_name(args), encoding="utf-8") as f:
