https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=34312 Bug ID: 34312 Summary: Advanced Editor - Rancor - Restore UNIMARC encoding support Change sponsored?: --- Product: Koha Version: unspecified Hardware: All OS: All Status: NEW Severity: critical Priority: P5 - low Component: Cataloging Assignee: koha-bugs@lists.koha-community.org Reporter: synapse.ova@gmail.com QA Contact: testopia@bugs.koha-community.org CC: m.de.rooy@rijksmuseum.nl Starting from at least version 22.11 opening UNIMARC bib records in advanced cataloging editor leaves only latin symbols and removes all other symbols (cyrillic, for example). At the same time, the record is opened normally in basic editor.

Code analysis shows that function marc8_to_utf8 is used, treating all utf8 symbols as marc8, therefore removing non ASCII characters. Looks like chosing of encoding is hardcoded for MARC21 (checked in record leader) and now is not compatible with UNIMARC (encoding is put in field 100). Encoding in MARC21 is stored in leader with character 09: " " (blank space) means coding is MARC-8 and "a" is UCS/Unicode (https://www.loc.gov/marc/bibliographic/bdleader.html) The same leader character 09 in UNIMARC in first editions should be blank (which is the case for most of our bib records). Since 2012 (https://cdn.ifla.org/wp-content/uploads/files/assets/uca/unimarc_updates/BIB...) this character is for Type of control: " " (blank space) means no specific type of control applies to the item being described and "a" is for Archival control. Since 2016 (https://cdn.ifla.org/wp-content/uploads/files/assets/uca/unimarc_updates/BIB...) "m" is added for Museum control. Therefore it is better to use the same code for discovering encoding as in basic editor. == Steps to reproduce the problem == The following steps are for UNIMARC Koha even though most likely the result would be the same on MARC21 as well. 1) Preliminary step 1. Check that advanced cataloging editor is enabled: Administration → System preferences → EnableAdvancedCatalogingEditor 2) Preliminary step 2. Check that bibliographical framework shows leader (000) and allows to edit it. 3) Open or prepare a bib record with non ASCII characters. For example, add αβγδεζηθικλμνξοπρστυφχψωæäåąßćęłńóśøöüźżабвгдежзийклмнопрстуфхцчшщьыъэюяёєїґўі’ to field 200$a or in other subfield. 4) Edit leader so that character 09 is blank. For example, paste " nam0 4500" (without quotation marks) 5) Switch to advanced editor. Settings → Switch to advanced editor. 6) Observe non-ASCII characters are gone The problem may be temporarily solved by user by changing character 09 in leader (field 000) to "a". -- You are receiving this mail because: You are the assignee for the bug.
