Subject: [PATCH] Bug 28094: Deal with encoding for overriden sysprefs
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The string we retrieved is UTF-8 encoded, to prevent encoding issue we
must decode it first.

Test plan:
Easily testable with LibraryName:
1. edit /etc/apache2/sites-available/kohadev.conf
2. Add
  RequestHeader add X-Koha-SetEnv "OVERRIDE_SYSPREF_LibraryName Library of ❤️"
3. restart_all
4. Hit the mainpage and look at the source (or title) and confirm that
the string is displayed correcty
