| Summary | 0001740: LC_COLLATE NUL (ISO/US-002) | ||||
| Description | In Volume 1, under 7.3.2.4, the definition of LC_COLLATE does not preclude the possibility that NUL is not at the beginning of the collation ordering. There are no C interfaces defined by POSIX that allows observation of such ordering of NUL; however, such ordering appears to be observable via the string comparison facility of the `test` utility in environments that both treat the utility as intrinsic and allow NUL characters in shell strings (perhaps via command substitution). The C++ standard library specifies interfaces that would allow observation of such ordering of NUL; however, the lack of standardized C interfaces with such capability means that C++ standard library implementations suffer in terms of quality or portability. localedef is a POSIX facility that serves as a source for locales with exotic sorting of NUL, so it seems within the scope of POSIX to declare that sorting under locales where NUL does not sort as the least value is subject to limitations. | ||||
| Desired Action | Specify that placing NUL in the collation order in any position other than the first need not succeed in all contexts. | ||||

On page 140 line 4644 section 7.3.2, after:Note: Users installing their own locales should ensure that they define a collation sequence with a total ordering of all characters unless an '@' modifier in the locale name (such as @icase) indicates that it has a special collation sequence.add: As <NUL> is reserved as the string terminator for most usages of LC_COLLATE, it is the responsibility of the locale writer to ensure <NUL> has the lowest primary weight in a collation ordering for the interfaces to behave in the way users typically expect. Unusual behavior may result if it has any other collation order weighting, or is subject to IGNORE. On page 144 line 4795 section 7.3.2.4, after: add:order_start forward;backward <NUL> <NUL>;<NUL> |
