Not possible to read a pdf from file system

If we try to read a pdf on file system  without ingesting into database

for $IMPORT in xdmp:filesystem-directory("C:\ABC\0000001\Import")/dir:entry
let $Batchfilename := $IMPORT/dir:filename
let $BatchPathname := $IMPORT/dir:pathname
for $EachBatchPath in xdmp:filesystem-directory($BatchPathname)
let $PDFDocumentPath := xdmp:filesystem-directory($EachBatchPath/dir:entry/dir:pathname)/dir:entry[cts:contains(dir:filename,cts:word-query(".pdf"))]/dir:pathname
 
let $EachInputFileContent := if (xdmp:filesystem-file-exists($PDFDocumentPath) ) then
                                              xdmp:filesystem-file($PDFDocumentPath)
                                            else ( )
 return
  xdmp:save("D:/test", $EachInputFileContent,
          <options xmlns="xdmp:save">
          <output-encoding>utf-8</output-encoding>
          </options>)


throws  error : XDMP-READFILE: $r instance of node()+ -- ReadFile File is not in UTF-8: 

Solution is to establish xcc/mljam connection to access java code to read a pdf
