However, different font designs are not considered to re

27、quire separate characters: where the shape, size or positioning of a character is meaningful within the citation, this will be specified by control characters. 6.2 Since characters have been assigned to the set on the grounds of shape rather than meaning, the absence of an appropriate definition by

28、a symbol, or appearance of such a definition by another symbol, does not imply a restriction against the use of that symbol in interchange of information in the form in which it appears in the data to be transmitted. 6.3 Names were chosen based on a commonly accepted term describing a characters sha

29、pe or function. For bibl iograph ic mathema tical characters that rep- resent several functions, a term descri bing their shape was preferred. References from alternative names, such as those provided in IS0 31-l 1, have been given in the “Comments” column. 6.4 Characters already appearing in an est

30、ablished character set are not generally repeated in the mathematical character set. Exceptions are, in table 1 the characters 2/9, 2/l 0, 2/l 2, 2/13 (non-spacing), 3/l d 3/13, 4/13 (also found in IRV), 7/O, 7/l (also found in IS0 54261, 5/O and 6/O (used as minus only) (also found in IRV), 3/15 an

31、d 4/15 (in smaller form in IS0 5428), and in table 2, 6/O (used as magnitude only) (also found in IRV). 6.5 Negative and other modified symbols may be constructed by combining symbols from this and/or other character sets by the use of non-spacing overlay facilities in table 1, column 2 of this set

32、or in other sets. 6.6 The codings given for each character in the legends are those recommended for use in environ- ments, such as teleprinter, which do not have access to the full character set. 13 IS0 6862: 1996( El Annex A (informative) PI 51 Bibliography IS0 31-I I :1992, Quantities and units -
