12、ns used for Latin abbreviations and contractions can vary considerably in meaning. Early printers (and those who have since copied their typography in bibliographic records) followed the manuscript tradition” In that tradition, common words, or endings which could be determined by context, were cont
13、racted and abbreviated. The actual signs used were only of secondary importance. The examples given in table 2 are not prescriptive. The choice of a character should be determined by the mark being reproduced rather than a strict adherence to the apparent meaning. 6.3 The characters coded in column
14、4 (positions 40 to 4C in table 1) represent combining marks which are non- spacing characters, that is, characters whose use is not followed by the forward movement of an output device. In a character string, these non-spacing characters are input before the characters they modify. Multiple combinin
15、g marks associated with one letter are to be encoded in the order in which they appear, reading from left to right or top to bottom. They are intended to be combined with other spacing characters in this International Standard or characters from the basic Latin set. The BACKSPACE character (hexadeci
16、mal code 08 in lSO/IEC 646) should not be used when encoding non-spacing characters. 6.4 The rendering of graphic characters is intended solely to identify uniquely these extended Latin script letters. The graphics used do not necessarily represent the most desirable calligraphic forms. 6.5 The name
17、s of characters (but not codes) have been made to correspond as much as possible to those assigned in lSO/IEC 10646-I.
