Returns the internal pathname in generic pathname format, converted to specific string type. Conversion, if any, is specified as follows:

[edit]

- 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.

The `/` character is used as the directory separator.

1) All memory allocations are performed by `a`.
2) The result encoding in the case of `u8string()` is always UTF-8.

### [edit] 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)

### [edit] Return value

The internal pathname in generic pathname format, converted to specified string type.

### [edit] Exceptions
