However, different font designs are not considered to require separate charact
30、ers: 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 a symbol, or appearanc
31、e 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 character s shape or function. For b
32、ibl 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 established character se
33、t 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 and 4/15 (in smaller fo
34、rm 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 or in other sets. 6.6
35、 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 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical St
