Cannot save page when there is a special character on buffer

[accidentalrebel]

Overview

There is a problem when saving a page if there is a special character on the buffer.

I found the bug when I tried saving a buffer with the pound sterling (£) symbol.

Here is the error that appears:

error in process sentinel: url-http-create-request: Multibyte text in HTTP request: POST /lib/exe/xmlrpc.php HTTP/1.1

The error message is followed by the xml details that was supposed to be sent.

How to replicate

Create a .dwiki buffer, add a pound sterling (£) symbol to it, then save it. The error should appear.

® was the culprit for me, found (and removed) with non ascii regex search: C-M-r [[:nonascii:]]
