Sorry, I meant that I could not produce a Help buffer.

I am not sure how to do it with Edebug. With (setq debug-on-error t) I
get this:
Debugger entered--Lisp error: (cl-assertion-failed ((not (multibyte-string-p
str)) nil))
cl--assertion-failed((not (multibyte-string-p str)))
encoded-string-description(#("😀" 0 1 (charset unicode)) nil)
describe-char(146)
what-cursor-position((4))
funcall-interactively(what-cursor-position (4))
call-interactively(what-cursor-position nil nil)
command-execute(what-cursor-position)
> Someone else reported that this started happening after upgrading

Yes, I am on HarfBuzz v5.1.0 as well. I will check that thread as well.
