From: Adam Dickmeiss Date: Thu, 18 Jan 2007 14:45:05 +0000 (+0000) Subject: Fixed bug #826: Weird looking chars for set of MARC records. X-Git-Tag: YAZ.2.1.48~12 X-Git-Url: http://sru.miketaylor.org.uk/?a=commitdiff_plain;h=60b5f5ba6f34ef79b037eb8af1e2554d9842bb10;p=yaz-moved-to-github.git Fixed bug #826: Weird looking chars for set of MARC records. Problematic record in test/marc8.marc . The record switched to MARC-8 mode 'Basic Arabic', then back to 'basic Hebrew' (and never back to Latin1/ASCII). --- diff --git a/src/marcdisp.c b/src/marcdisp.c index f77482f..02f3d3e 100644 --- a/src/marcdisp.c +++ b/src/marcdisp.c @@ -2,7 +2,7 @@ * Copyright (C) 1995-2007, Index Data ApS * See the file LICENSE for details. * - * $Id: marcdisp.c,v 1.43 2007-01-06 16:08:04 adam Exp $ + * $Id: marcdisp.c,v 1.44 2007-01-18 14:45:05 adam Exp $ */ /** @@ -125,6 +125,27 @@ NMEM yaz_marc_get_nmem(yaz_marc_t mt) return mt->nmem;
