EACC and Unicode are available from the Library of Congress. Punctuation, symbol, kana and jamo charts Following are charts for punctuation, symbols, kana and Hangul jamo, showing the characters and giving possible Unicode mappings. Where possible, these are referenced against published mapping data. Unicode mappings for Hangul syllables are omitted below for brevity, but are documented by the Library of Congress. CCCII hanzi number in the tens of thousands and are not shown below (except where they are also included in the non-hanzi range, as radicals or numerals), but mappings to Unicode are available from the Unihan database and from elsewhere. Character set 0x2120 (plane 1, row 0: Hong Kong punctuation) Although CCCII is usually a 94n set, and therefore does not usually use codes starting with 0x2120, the following layout is used by a variant used by libraries in Hong Kong: Character set 0x2121 (plane 1, row 1: reserved for controls) No characters are assigned in plane 1 row 1, which is reserved for control codes. Character set 0x2122 (plane 1, row 2: mathematical operators) This row contains mathematical operators. EACC leaves this row empty. The following table is referenced against sources from Taiwan. The following table is referenced against CCCII data provided by the Hong Kong Innovative Users Group, a group of libraries in Hong Kong, and hosted by the University of Hong Kong. It uses an entirely different layout in this row: Character set 0x2123 (plane 1, row 3: Roman and punctuation) This row includes punctuation, western Arabic numerals and Roman letters. Compare row 3 of Wansung code and row 3 of GB 2312. Different variants variously encode the ideographic space (U+3000) at 0x212320 (which the MARC specification acknowledges), 0x212321 (which is listed in the ANSI standard, and is also acknowledged by MARC), or 0x21635F. EACC includes only the hyphen-minus, parentheses and ideographic space in this set. Character set 0x212A (plane 1, row 10: internal IME characters and geta mark) In EACC, this row includes several Private Use Area mapped characters used internally to represent character components by the RLIN input method, which is used by the Library of Congress for non-Roman cataloging. These component characters should only be used internally by an IME and, if encountered elsewhere, may be replaced with the geta mark (U+3013), which this row also includes at 0x212A46. This row is unassigned in CCCII, but the geta mark is also listed at
