`papers/by/AUTHOR` page doesn't work for names containing period characters

[kandersolar]

On the page for published papers, the list of author names in the side bar is hyperlinked to a page listing all publications by each author. However, that page seems broken (HTTP 406) for author names containing a period, at least on Chrome -- I observe no issues with Firefox.

Here is an example:

• Paper page: https://joss.theoj.org/papers/10.21105/joss.06714
• Broken link: https://joss.theoj.org/papers/by/James%20P.%20Ewen

Deleting the "." in the URL gets it working for me.
