Note that this is different from the POSIX command line utilities, // which convert according to a locale. // // Thus for POSIX, char strings do not undergo conversion. wchar_t strings // are converted to/from char using the path locale or, if a conversion // argument is given, using a conversion object modeled on // std::wstring_convert. // // The path locale, which is global to the thread, can be changed by the // imbue() function. It is initialized to an implementation defined locale. // // For Windows, wchar_t strings do not undergo conversion. char strings // are converted using the "ANSI" or "OEM" code pages, as determined by // the AreFileApisANSI() function, or, if a conversion argument is given, // using a conversion object modeled on std::wstring_convert. // // See m_pathname comments for further important rationale. // TODO: rules needed for operating systems that use / or . // differently, or format directory paths differently from file paths. // // ********************************************************************************** // // More work needed: How to handle an operating system that may have // slash characters or dot characters in valid filenames, either because // it doesn't follow the POSIX standard, or because it allows MBCS // filename encodings that may contain slash or dot characters. For // example, ISO/IEC 2022 (JIS) encoding which allows switching to // JIS x0208-1983 encoding. A valid filename in this set of encodings is // 0x1B 0x24 0x42 [switch to X0208-1983] 0x24 0x2F [U+304F Kiragana letter KU] // ^^^^ // Note that 0x2F is the ASCII slash character // // ********************************************************************************** // Supported source arguments: half-open iterator range, container, c-array, // and single pointer to null terminated string. // All source arguments except pointers to null terminated byte strings support // multi-byte character strings which may have embedded nulls. Embedded null // support is required for some Asian languages on Windows. // "const codecvt_type& cvt=codecvt()" default arguments are not used because this // limits the impact of locale("") initialization failures on POSIX systems to programs // that actually depend on locale("").
