bug#24239: 25.1; Potential regression: Multibyte text in HTTP request

[Damien Cassou]

I'm using Emacs 25 rc1 and org-caldav from
https://github.com/dengste/org-caldav. The function #'org-caldav-sync
(https://github.com/dengste/org-caldav/blob/master/org-caldav.el#L524)
raises an error when a local event with accented characters is sent to
the remote cardav server.

When I switch to Emacs 24, the synchronization works perfectly.
