Unicode path names are not supported

All previous steps works fine before saving the data in python format. Jupyter Notebook refuses to open the updated ipython output with the below message:

An unknown error occurred while loading this notebook. This version can load notebook formats v4 or earlier. See the server log for details.

Thanks Bruno for reporting. Could you please share the server logs (i.e. what was printed in the console where you run jupyter notebook)? Or even the modified python script? Thanks

Useful details, thanks. Can you change the notebook name so that it only has ASCII characters for now? Does that solve the issue?

[BrunoYang0918]

Hi Marc, Thanks for the reply. Your suggestion works when the path and file name are all changed to ASCII characters. Only change the names would not work. My issue is solved, thanks a ton. This is a great tool, I would use this from now on. Best, Bruno

I'm glad you like it! Thanks. Please do not close the issue yet - I will implement one more test, and a bugfix, to be sure that you can use unicode file and path names in the next version.

[mwouts]

@BrunoYang0918 , could you please upgrade to v0.6.4 and confirm whether you issue is resolved?

pip install jupytext==0.6.4
# + restart jupyter notebook

Thanks

[BrunoYang0918]

Hi Marc, Let me try this. Will let you know once confirmed. Best, Bruno

Great news! Thanks for the feedback.

[mppaskov]

Not sure if this is related but I had a notebook named 1.Some Notebook.ipynb and it was not exporting automatically to .py. Even after manually exporting the notebook with the command line it would not sync. Was able to fix this by renaming the notebook Some Notebook.ipynb.

[mwouts]

Thanks @mppaskov for reporting. I will add your example as a unit test.

Please let me recall that you cannot expect notebook to export and sync automatically! If you want a notebook to be saved into both extensions, you have to add the "jupytext_formats": "ipynb,py" entry in the metadata (alternatively, a global config is possible, cf. the documentation ).

Also, the command line tool is not going to add that metadata, so it is not enough to create the .py file manually.

I agree that editing the notebook metadata is not very user friendly. At some point we will provide a Jupyter extension (i.e. buttons in the jupyter notebook) to make that easier, see #86.

[mwouts]

@mppaskov , I think I can reproduce your issue. Please follow progresses on that at #87. Thanks for letting me know!
