bibtex example fails to compile

[simonbyrne]

The url in the sample bibtex returns the following error:

 Your paper failed to compile with the following errors:

Looks like we failed to compile the PDF with the following error: Error producing PDF. ! TeX capacity exceeded, sorry [input stack size=5000]. \reserved@a ->\def \reserved@a *{\@hspacer }\reserved@a l.500 ...pace{0pt}https://github.com/arfon/fidgit} 

This appears to refer to this bibtex entry:

@misc{fidgit,
  author = {​A. Smith},
  title = {Fidgit: An ungodly union of GitHub and Figshare},
  year = {2020},
  publisher = {​GitHub},
  journal = {​GitHub repository},
  url = {​https://github.com/arfon/fidgit}
}

This can be reproduced by running the whedon preview on this repository:
https://github.com/simonbyrne/testjoss
(which is basically the sample from the above link with the figure references removed).
