|Date of presentation of proposal:
|ISO/IEC JTC 1/SC 22 N 3356|
A proposal for a new work item shall be submitted to the secretariat of the ISO/IEC joint technical committee concerned with a copy to the ISO Central Secretariat.
Presentation of the proposal - to be completed
by the proposer Guidelines for proposing and justifying a new work item
are given in ISO Guide 26.
Specification for additional character data types to the programming language C.
To introduce additional character data types and corresponding character and string literals to the programming language C (as defined in ISO/IEC 9899:1999). This will allow support for encodings such as UTF-16 in a portable way, examples will be included to show the use of these new data types. The relationship between the existing (char and wchar_t) character data types and the new types will be explained, a rationale for the choices made will also be documented.
|Purpose and justification
The programming language C as specified by the International Standard ISO/IEC 9899:1999 provides two data types for character processing: char and wchar_t. For these data types a set of library functions is also specified.
|Programme of work
If the proposed new work item is approved, which of the following
document(s) is (are) expected to be developed?
|Relevant documents to be considered
|Cooperation and liaison
All ISO/IEC JTC 1/SC22 Working groups that have an interest in supporting many natural languages, especially ISO/IEC JTC 1/SC22 WG21 (C++).
|Preparatory work offered with target
A PDTR document will be ready for registration 24 months after the approval of the project by JTC 1.
|Will the service of a maintenance agency
or registration authority be required? .......NO.............
- If yes, have you identified a potential candidate? ................
- If yes, indicate name .............................................................
Are there any known requirements for coding? ..........NO.........
Are there any known requirements for cultural and linguistic
Does the proposed standard concern known patented items?

Notes to Proforma
A. Business Relevance. That which identifies market place relevance in terms of what problem is being solved and or need being addressed.
A.1. Market Requirement. When submitting a NP, the proposer shall identify the nature of the Market Requirement, assessing the extent to which it is essential, desirable or merely supportive of some other project.
A.2 Technical Regulation. If a Regulatory requirement is deemed to exist - e.g. for an area of public concern e.g. Information Security, Data protection, potentially leading to regulatory/public interest action based on the use of this voluntary international standard - the proposer shall identify this here.
B. Related Work. Aspects of the relationship of this NP to other areas of standardization work shall be identified in this section.
B.1 Competition/Maintenance. If this NP is concerned with completing or maintaining existing standards, those concerned shall be identified here.
B.2 External Commitment. Groups, bodies, or fora external to JTC1 to which a commitment has been made by JTC for cooperation and or collaboration on this NP shall be identified here.
B.3 External Std/Specification. If other activities creating standards or specifications in this topic area are known to exist or be planned, and which might be available to JTC1 as PAS, they shall be identified here.
C. Technical Status. The proposer shall indicate here an assessment of the extent to which the proposed standard is supported by current technology.
C.1 Mature Technology. Indicate here the extent to which the technology is reasonably stable and ripe for standardization.
C.2 Prospective Technology. If the NP is anticipatory in nature based on expected or forecasted need, this shall be indicated here.
C.3 Models/Tools. If the NP relates to the creation of supportive reference models or tools, this shall be indicated here.
D. Any other aspects of background information justifying this NP shall be indicated here.
D. Conformity Assessment and Interoperability
D.1 Indicate here if Conformity Assessment is relevant to your project. If so, indicate how it is addressed in your project plan.
D.2 Indicate here if Interoperability is relevant to your project. If so, indicate how it is addressed in your project plan.
