Use PyUnicode_FromObject() to convert the (non-string) object to a unicode
object, then encode the unicode object as UTF-16 using the respecive
functions in the codecs API (see the bottom of the C-API docs page for the
Note, however, that you will not succeed to convert a byte string to the
corresponding unicode string using PyUnicode_FromObject(), except in the
simple case where the string is ASCII encoded. Doing this right requires
explicit decoding using a byte encoding that you must specify (again, see
the codecs API).
