std::experimental::filesystem::path::path

1) Constructs an empty path.

2) Copy constructor. Constructs a copy of p.

3) Move constructor. Constructs a copy of p, p

4,5) Constructs the path from a character sequence provided by source (4), which is a pointer or an input iterator to a null-terminated character/wide character sequence or an std::basic_string, or represented as a pair of input iterators [first, last) (5). Any of the four character types char, char16_t, char32_t, wchar_t is allowed, and the method of conversion to the native character set depends on the character type used by source.

• If the source character type is char
• If the source character type is char16_t, conversion from UTF-16 to native filesystem encoding is used.
• If the source character type is char32_t, conversion from UTF-32 to native filesystem encoding is used.
• If the source character type is wchar_t, the input is assumed to be the native wide encoding (so no conversion takes places on Windows).

6,7) Constructs the path from a character sequence provided by source (6), which is a pointer or an input iterator to a null-terminated character sequence or an std::string, or represented as a pair of input iterators [first, last) (7). The only character type allowed is char. Uses loc to perform the character encoding conversion. If value_type is wchar_t, converts from to wide using the std::codecvt < wchar_t, char, std::mbstate_t > facet of loc. Otherwise, first converts to wide using the std::codecvt < wchar_t, char, std::mbstate_t > facet and then converts to filesystem native character type using std::codecvt < wchar_t, value_type> facet of loc
