Subject: Added zebra_octet_term_encoding that specifies encoding for search
X-Git-Tag: snippet.version.1~206
X-Git-Url: http://git.indexdata.com/?p=idzebra-moved-to-github.git;a=commitdiff_plain;h=be946e8fca9b807679467d508ccfe0f4b450f2d0

Added zebra_octet_term_encoding that specifies encoding for search
octet string search terms. Default record encoding is NULL - not
ISO-8859-1. This potentially breaks some applications, but it allows
for _no_ character set conversion for MARC records and others.
