Katrin Fischer bfeac64865 Bug 22075: Fix encoding problem with RIS export in OPAC
When exporting a record with diacritics in RIS
format from the detail page in OPAC the encoding
is not correct and the diacritics appear broken.

This patch fixes it.

To test:
- Find or create a record with some special
  chars in your OPAC
- Go to the detail page
- Save as > RIS
- Verify the diacritics are broken in an editor
- Apply patch
- Repeat and verify everything now displays correctly
