Brief History As part of the work on coded character set standards, TC1, the coding com

3、mittee of ECMA, worked on the definition and the coding of control functions to be used with the various standards for coded graphic character sets produced by ECMA, viz. ECMA-6, ECMA-94, ECMA-113, ECMA-114, ECMA-118, ECMA-121, ECMA-128, and ECMA-144. The first edition of this Standard ECMA-48 was p

4、ublished in 1976. Further editions followed. The fourth edition, published in 1986 was adopted by ISO/IEC under the fast-track procedure as second edition of ISO 6429. It constitutes a repertoire of a large number of control functions the definitions and coded representations of which are thus stand

5、ardized. For each application the required selection of control functions can be made from this repertoire. This fifth edition of Standard ECMA-48 contains the control functions already standardized in the fourth edition and, in addition, new control functions needed for handling bi-directional text

6、s, i.e. texts comprising parts written with a left-to-right script and parts written with a right-to-left script. ECMA Technical Report TR/53 gives further information and examples of handling such texts. The inclusion of these specialized control functions has required a corresponding adjustment of

7、 the definitions of some of the other control functions. Moreover, the concept of “device“ had to be revised. This fifth edition has been contributed to ISO/IEC for adoption under the fast-track procedure as third edition of ISO/IEC 6429. Adopted by the General Assembly of ECMA on 13th June 1991. -

45、 ECMA-48 87 - viii - . 1 Scope This ECMA Standard defines control functions and their coded representations for use in a 7-bit code, an extended 7-bit code, an 8-bit code or an extended 8-bit code, if such a code is structured in accordance with Standard ECMA-35. The control functions defined in thi

46、s Standard are intended to be used embedded in character-coded data for interchange, in particular with character-imaging devices. In general, the control functions are defined by their effects on a character-imaging input/output device. It is, therefore, necessary to make certain assumptions about

47、the architecture of such a device. These assumptions are as unrestrictive as possible; they are specified in clause 6. In addition to being performed the control functions may need to be represented by a graphic symbol. The structure of this Standard is open-ended, so that more control functions can

48、 be included in future editions. Other standards specifying control functions may define more restricted definitions of them than those in this Standard. The devices to which this Standard applies can vary greatly from each other depending on the application for which a device has been specifically

49、designed. It is technically and economically impractical for one device to implement all the facilities specified in this Standard. The intention is that in any type of device only a limited selection of the facilities appropriate to the application will be implemented. 2 Conformance 2.1 Types of conformance Full conformance to a standard means that all of its requirements are met. Conformance will only have a unique meaning if the standard contains no options. If there are options within the standard they must be clearly identified, and any claim of conformance must include a statement
