2、ue - Partie 3: Dispositions complkmentaires de la zone alphanum - a national keyboard layout established by common usage in a particular country; - the complementary Latin group layout as defined in clause 6 of this part of ISO/IEC 9995. NOTE 2 Refer to annex A of part 2 of ISO/IEC 9995 for examples

3、 of allocations of graphic characters to the primary group of the alphanumeric zone of the alphanumeric sec- tion. NOTE 1 The full repertoire of ISO/IEC 6937 permits the representation of 40 recognized European languages (plus Afrikaans) using a Latin-based alphabet. This part of ISO/IEC 9995 is pri

4、marily intended for word-processing and text-processing applications. Any statement of conformance to this International Standard shall be taken to imply that the complete common secondan/ group layout (Group 2) has been implemented, unless a subset is explicitly declared, provided that all other re

5、quirements of clause 5 are respected. 2 Conformance 3 Normative references The layout of a keyboard conforms to this part of ISO/IEC 9995 if the allocation of the graphic charac- ters of the common secondary group (group 2) is as defined in clause 5 of this part of ISO/IEC 9995, and if the allocatio

6、n of the graphic characters of the pri- mary group (group I) conforms to one of the following layouts: The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO/IEC 9995. At the time of publi- cation, the editions indicated were valid

10、ven in ISO/IEC 9995-l apply. 5 Common secondary group layout The common secondary group layout specified in ISO/IEC 9995-3 requires a keyboard with 48 graphic keys according to ISO/IEC 9995-2. This layout re- quires the provision of a second group as defined in ISO/IEC 9995-l. The graphic characters

11、 of group 1 and the layout of these on the keyboard are defined by the relevant national keyboard layout standard or established by common usage. The graphic charac- ters of the common secondary group (group 2) are those of the repertoire of ISO/IEC 6937 that are not found as group 1 characters in a

12、ll national keyboard layouts nor in layouts established by common usage in a particular country. This leads to a certain dupli- cation of graphic characters between the group 1 lay- outs and the layout of the common secondan/ group (group 2). However, it allows the graphic characters of the common s

13、econdary group and their allocation to keys to be always the same for their use with any established Latin group layout. The allocation of the characters of the common sec- ondary group (group 2) shall be as defined in table 1. ame I - Auocar:Ion 01 me grapnic cnaracfers of the common secondary grou

It is not

18、mandatory to show the graphic symbols of all graphic characters on keytops. Duplicates of pri- mary group 1 graphic characters should not be shown in group 2. Where small and capital forms of a letter exist, only the capital form need be shown. The names of the graphic characters shown in the table

19、are those used for the equivalent coded graphic characters in other ISO/IEC Standards, for example in the most recent versions of ISO/IEC 6937 or of ISO/IEC 10367. The convention there is to use capital letters for the names to indicate that they are coded graphic characters. As this part of this In

20、ternational Standard does not specify coding, the convention of using only capital letters was not retained here. Otherwise the names of the graphic characters are identical with those in the relevant ISO/IEC coding standards. The names chosen to denote the graphic characters are intended to reflect

21、 their customary meaning. However, this part of this International Standard does not define and does not restrict the meanings of graphic characters. Nor does it specify a particular style or font design for imaging the graphic charac- ters. 5.1 Operation of keys with diacritical marks Diacritical m

22、arks are the following: Acute Accent Breve Caron Cedilla Circumflex Accent Diaeresis Dot Above Double Acute Accent Grave Accent Matron Ogonek Ring Above Tilde. NOTE 4 Dot below, which is also allocated to a key, is a diacritical mark not defined in ISO/IEC 6937. Diacritical marks appear above or bel

23、ow certain let- ters, and all of them are non-spacing characters. Ac- tuating a key with a diacritical mark, followed by actuating a key with a letter, shall indicate that the graphical symbols of the two characters are intended to be combined. Actuating a key with a diacritical mark, followed by ac

24、tuating the space bar, shall indi- cate that the diacritical mark is intended to appear as a graphic character of its own (i.e. free-standing). 3 ISO/IEC 9995-3:1994(E) 0 ISO/IEC It is recommended that the method used for the de- letion of a character should also be used to cancel a partially-constr

25、ucted character, such as a diacritical mark without a following letter or a following Space character. 6 Complementary Latin group layout The complementary Latin group layout specified in ISO/IEC 9995-3 requires a keyboard with 48 graphic keys according to ISO/IEC 9995-2. This complemen- tary layout

26、 is provided for those cases where no na- tional keyboard layout standard or common national usage keyboard layout is available. It may also be used in those cases when the primary layout is based on a non-Latin script. The allocation of the characters of the complementary Latin group shall be as de

27、fined in table2. It is not mandatory to show the graphic symbols of all graphic characters on keytops. Duplicates of other primary group 1 graphic characters should not be shown in group 2. Where small and capital forms of a letter exist, only the capital form need be shown. The names of the graphic

28、 characters shown in the table are those used for the equivalent coded graphic characters in other ISO/IEC Standards, for example in the most recent versions of ISO/IEC 6937 or of ISO/IEC 10367.
