[Koha-patches] [PATCH] Bugfixes #2773 - Hide NSB and NSE characters

[Frederic Demians]

MARC21 and UNIMARC biblio records can contains non-sorting special
characters, NSB and NSE. For details:

  http://www.loc.gov/marc/nonsorting.html

Those characters are improperly displayed by web browsers as a square
containing character hexadecimal value (88 ou 89). 

This patch filters NSB and NSE when reading biblio records
from DB (not from Zebra).
