À l'exception de l'eszett (ß ou ſʒ) et du symbole euro (€), tous les caractères figurant dans le <https://www.marc21.ca/M21/M9230.html tableau des codes MARC] peuvent être utilisés dans les notices d'autorité ajoutées au fichier d'autorité Canadiana ([http://original.rdatoolkit.org/lcpschp1_lcps1-39.html voir LC-PCC PS pour 1.4]). Lorsque des données provenant d'un site Web sont copiées/collées dans une zone 670, vérifier que tous les caractères peuvent être utilisés dans la notice.

With the exception of the eszett (ß or ſʒ) and the euro sign (€), all characters found in the MARC code table (http://www.loc.gov/marc/specifications/specchartables.html) are valid for use in authority records contributed to the LC/NACO Authority File (see LC-PCC PS 1.4). When pasting data from a website into a 670 field, verify that all characters are valid for use in the record. Some non-valid characters resemble those that are valid. For example, the invalid en dash (–) resembles the valid hyphenminus (-).
