Re: re-generate the PDF with standard non-embedded fonts

let me  explain exactly what i want here  .i am using xpdf to convert pdf files into html or txt
i have a original pdf attached. 
root@6334724bdee5:/tmp# pdffonts 1.pdf name                                 type              encoding         emb sub uni object ID ------------------------------------ ----------------- ---------------- --- --- --- --------- SRPUEP+SimSun                        TrueType          WinAnsi          yes yes yes     13  0 root@6334724bdee5:/tmp# pdfinfo 1.pdf  Creator:        Online2PDF.com Producer:       Online2PDF.com CreationDate:   Sat Aug 13 07:42:20 2016 UTC Tagged:         no UserProperties: no Suspects:       no Form:           none JavaScript:     no Pages:          1 Encrypted:      no Page size:      594.75 x 419.25 pts Page rot:       0 File size:      31707 bytes Optimized:      no PDF version:    1.4 root@6334724bdee5:/tmp# pdftohtml  1.pdf  1-output.html
as https://github.com/mozilla/pdf.js/issues/7712 suggest "Looks like PDF removed character encoding ",
is there any way to recreate this pdf through original one  ?then I can copy the text from it instead of mess http://stackoverflow.com/questions/12703387/pdf-font-encoding-why-cant-i-copy-text-from-a-pdf

There are tools for parsing PDFs like the python tools listed at https://www.binpress.com/tutorial/manipulating-pdfs-with-python/167
 

 
 
You might be able to load the PDF, remove the objects with the embedded fonts, and write a new file, but if the embedded fonts are subsets or have non-standard encodings, the text might become unintelligible.

 Then you cannot use Ghostscript.
