Bug 12174 - Zotero connection with Koha: problem with UTF-8

This patch solves the bug for UTF-8 output. MARC-8 works only if you save it as a file. In fact the standard Internet stack (browser, web server, etc.) doesn't know anything about MARC-8 or it's ISO base (ISO 2022).

To test the bug:
-- without the patch use Zotero on a recent Koha install with Apache.
You can use PTFS sandboxes. You can't use Biblibre sandboxes, they use Ngix.
-- Test a record with special chars.
-- Install the patch
-- Catch (using Zotero) the same record.
-- Test all directly download from Opac.
-- To check MARC-8, use a tool that support it. For example MarcEdit.

Work as described
Tested with zotero add-on for firefox.
Before patch bad diacritics, after patch ok

Record exported as MARC-8, transformed using
yaz-iconv -f marc8 -t utf-8 bib.marc8 > bib.utf8
yaz-marcdump -i marc -o line bib.utf8, checking accents,
also comparing with direct utf-8 export

No koha-qa errors
