Subject: Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8
X-Git-Tag: YAZ.2.1.54~14
X-Git-Url: http://git.indexdata.com/?p=yaz-moved-to-github.git;a=commitdiff_plain;h=19c0b332044f06ee33eaf66ca92675d9cda8d1b9

Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8
combo sequence is met. Before the error was not set so it would
be unknown.
