Returns the internal pathname in generic pathname format, converted to specific
string type. Conversion, if any, is specified as follows:
* If path::value_type is char, conversion, if any, is system-dependent. This is
the case on typical POSIX systems (such as Linux), where native encoding is
UTF-8 and string() performs no conversion.
* Otherwise, if path::value_type is wchar_t, conversion, if any, is unspecified.
This is the case on Windows, where wchar_t is 16 bit and the native encoding is
UTF-16.
* Otherwise, if path::value_type is char16_t, native encoding is UTF-16 and the
conversion method is unspecified.
* Otherwise, if path::value_type is char32_t, native encoding is UTF-32 and the
conversion method is unspecified.
* Otherwise, if path::value_type is char8_t, native encoding is UTF-8 and the
conversion method is unspecified.
The / character is used as the directory separator.
1) All memory allocations are performed by a.
3) The result encoding in the case of u8string() is always UTF-8.
Parameters
a - allocator to construct the string with
Type requirements
-
CharT must be one of the encoded character types
(char, wchar_t, char16_t and
char32_t)
Return value
The internal pathname in generic pathname format, converted to specified string
type.
Exceptions
(none)

u8string (public member function)
u16string
