Clone object into pdf_dest (PdfWriterProtocol which is an interface for PdfWriter).
By default, this method will call ``_reference_clone`` (see ``_reference``).
Args:
pdf_dest: Target to clone to.
force_duplicate: By default, if the object has already been cloned and referenced,
the copy will be returned; when ``True``, a new copy will be created.
(Default value = ``False``)
ignore_fields: List/tuple of field names (for dictionaries) that will be ignored
during cloning (applies to children duplication as well). If fields are to be
considered for a limited number of levels, you have to add it as integer, for
example ``[1,"/B","/TOTO"]`` means that ``"/B"`` will be ignored at the first
level only but ``"/TOTO"`` on all levels.
Returns:
The cloned PdfObject

Represents a string object where the text encoding could not be determined.
This occurs quite often, as the PDF spec doesn't provide an alternate way to
represent strings -- for example, the encryption data stored in files (like
/O) is clearly not text, but is still stored in a "String" object.

A string object that has been decoded into a real unicode string.
If read from a PDF document, this string appeared to match the
PDFDocEncoding, or contained a UTF-16BE BOM mark to cause UTF-16 decoding
to occur.

It is occasionally possible that a text string object gets created where
a byte string object was expected due to the autodetection mechanism --
if that occurs, this "original_bytes" property can be used to
back-calculate what the original encoded bytes were.
