Hello,



Per the size of the MARC21 bibliographic record, the record length is defined in the Leader<https://www.loc.gov/marc/bibliographic/bdleader.html> position 00-04, 5 characters, and the maximum length of a record is 99999 octets. The length of the field is defined in the Directory<https://www.loc.gov/marc/bibliographic/bddirectory.html> position 03-06, 4 characters, thus a field may contain a maximum of 9999 octets. In general, it should be enough to record the data.



MARC21 bibliographic records can be expressed in either MARC-8 character repertoire, or Unicode. LC maintains the mapping document<https://www.loc.gov/marc/specifications/specchartables.html> between MARC-8 to Unicode. More libraries have adopted Unicode, and many library systems provide the option to accept and output records in MARC-8 and/or Unicode. For languages with diacritics, there could be system preference on whether to accept and/or convert the inputted pre-composed diacritics to decomposed diacritics (i.e., convert é, U+00E9, to eì, U+0301).



For languages in multiple scripts<https://www.loc.gov/marc/bibliographic/ecbdmulti.html>, MARC21 offered two options:

Model A: Vernacular and transliteration: transcribe the script as found on the publication, and provide the corresponding transliteration data

Model B: Simple multiscript records: either transcribe the script only, or provide the transliteration data only



But again, library systems may choose to prefer either Model A or Model B.



Thanks,

Hong Cui
