i use beorg in ios 13, when i use this code ,
#+begin_src emacs-lisp :tangle yes '("https://www.zhihu.com/search?type=content&q=%s") #+end_src
the preview show this error code
It wasn't possible to render this document: URIError: URI error
I shall investigate what is going on - thanks for reporting.
I've implemented a fix for this and it will be in the next beorg update (hopefully next week).
