Assessment of Options for Handling Full Unicode Character Encodings in MARC21 a Study for the Library of Congress
1 Assessment of Options for Handling Full Unicode Character Encodings in MARC21 A Study for the Library of Congress Part 1: New Scripts Jack Cain Senior Consultant Trylus Computing, Toronto 1 Purpose This assessment intends to study the issues and make recommendations on the possible expansion of the character set repertoire for bibliographic records in MARC21 format. 1.1 “Encoding Scheme” vs. “Repertoire” An encoding scheme contains codes by which characters are represented in computer memory. These codes are organized according to a certain methodology called an encoding scheme. The list of all characters so encoded is referred to as the “repertoire” of characters in the given encoding schemes. For example, ASCII is one encoding scheme, perhaps the one best known to the average non-technical person in North America. “A”, “B”, & “C” are three characters in the repertoire of this encoding scheme. These three characters are assigned encodings 41, 42 & 43 in ASCII (expressed here in hexadecimal). 1.2 MARC8 "MARC8" is the term commonly used to refer both to the encoding scheme and its repertoire as used in MARC records up to 1998. The ‘8’ refers to the fact that, unlike Unicode which is a multi-byte per character code set, the MARC8 encoding scheme is principally made up of multiple one byte tables in which each character is encoded using a single 8 bit byte. (It also includes the EACC set which actually uses fixed length 3 bytes per character.) (For details on MARC8 and its specifications see: http://www.loc.gov/marc/.) MARC8 was introduced around 1968 and was initially limited to essentially Latin script only. -
Request to Annotate North Indian Quarter Signs for Malayalam Usage Cibu Johny [email protected] Shiju Alex [email protected] Sunil V S [email protected]
Request to Annotate North Indian Quarter Signs for Malayalam Usage Cibu Johny [email protected] Shiju Alex [email protected] Sunil V S [email protected] 2017‐Sep‐22 Introduction Malayalam has following fractions involving quarter: Malayalam Unicode chart: h ttp://unicode.org/charts/PDF/U0D00.pdf However, many 19th century Malayalam documents use the North Indian quarter forms as well. Those forms are: Common Indic Number Forms Unicode chart: h ttp://www.unicode.org/charts/PDF/UA830.pdf However, this is not indicated either in the Malayalam section of the standard nor in the Common Indic Number Forms. The ‘North Indic’ common prefix for the names of the fractions could imply that it is not used in Malayalam. 1 Attestations Attestations from various sources are listed below: 1856 The Malayalam Reader Charles Collet, CMS Press Cottayam, Page 4 1868 Kerala pazhama Basel Mission Press, Mangalore, Page 59 2 1873 Sreemahabharatham Vidyavilasam, Calicut, Cover page 1856 The Malayalam Reader Charles Collet, CMS Press Cottayam, Page 14,15 3 Annotation requests Request 1 The chart for Common Indic Number Forms needs to add following to U+A830, U+A830, and U+A830: ● Used in Malayalam also Request 2 The Malayalam chart should add following annotation: 0D73 ൳ MALAYALAM FRACTION ONE QUARTER → A830 ꠰ NORTH INDIC FRACTION ONE QUARTER 0D73 ൴ MALAYALAM FRACTION ONE HALF → A831 ꠱ NORTH INDIC FRACTION ONE HALF 0D73 ൵ MALAYALAM FRACTION THREE QUARTERS → A832 ꠲ NORTH INDIC FRACTION THREE QUARTERS Request 3 In section 12.9 Malayalam: Malayalam Numbers and Punctuation, following editorial change is required: Archaic Numbers. The characters used for the archaic number system, includes those for 10, 100, and 1000, and fractions. -
