+ //
+ // POSIX specfies that path strings are passed unchanged to and from the
+ // API. 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.
+
+ // [defaults] "const codecvt_type& cvt=codecvt()" default arguments are not used
