Jupyter Viewer: ellipsis character breaks the component

[labarba]

It looks like the viewer is unable to display content from a notebook when a cell contains the ellipsis character, u'\u2026' —see screenshot.

For now, since I want to finish this course, I will edit the source notebook and remove the character. But this should be fixed or it may trip others in the future.

Course I'm working on:

I used the em-dash (—) character in one End Tag, and the component breaks, too.

Hi @labarba,

Can you confirm if this is still an issue, or point me to a notebook that has this issue?

I just tried the following commit which looks like it has the ellipsis character in the Bubble Chart section and it looks like it's rendering properly.

Thanks!

I just tried to load a notebook with a horizontal ellipsis in the string for the "Start tag" and it fails.

The error says:

WE'RE HAVING TROUBLE RENDERING YOUR COMPONENT

Students will not be able to access this component. Re-edit your component to fix the error.

Error: 'ascii' codec can't encode character u'\u2026' in position 26: ordinal not in range(128)

The only option at that point is to delete the Unit, because it is not possible to edit the component any longer.
