I want to change the metadata of the pdf file using this code:
from PyPDF2 import PdfFileReader, PdfFileWriter title = "Vice-présidence pour l'éducation" fin = open(filename, 'rb') reader = PdfFileReader(fin) writer = PdfFileWriter() writer.appendPagesFromReader(reader) metadata = reader.getDocumentInfo() metadata.update({'/Title':title}) writer.addMetadata(metadata) fout = open(filename, 'wb') writer.write(fout) fin.close() fout.close() It works fine if the title is in english(no accents) but when it has accents I get the following error:
TypeError: createStringObject should have str or unicode arg How can I add a title with accent to the metadata ?
Thank you

The only way to get this error message is to have the wrong type for the parameter string in the createStringObject(string)-function in the library itself.
It's looking for type string or bytes using these functions in utils.py
import builtins bytes_type = type(bytes()) # Works the same in Python 2.X and 3.X string_type = getattr(builtins, "unicode", str) I can only reproduce your error if I rewrite your code with an obviously wrong type like this (code is rewritten using with statement but only the commented line is important):
from PyPDF2 import PdfFileReader, PdfFileWriter with open(inputfile, "rb") as fr, open(outputfile, "wb") as fw: reader = PdfFileReader(fr) writer = PdfFileWriter() writer.appendPagesFromReader(reader) metadata = reader.getDocumentInfo() # metadata.update({'/Title': "Vice-présidence pour l'éducation"}) metadata.update({'/Title': [1, 2, 3]}) # <- wrong type here ! writer.addMetadata(metadata) writer.write(fw) It seems that the type of your string title = "Vice-présidence pour l'éducation" is not matching to whatever bytes_type or string_type is resolved. Either you have a weird type of the title variable (which I cannot see in your code, maybe because of creating a MCVE) or you have trouble getting bytes_type or string_type as types intended by library writer (this can be a bug in the library or an erroneous installation, hard to tell for me).
Without reproducible code, it's hard to provide a solution. But hopefully this will give you the right direction to go. Maybe it's enough to set the type of your string to whatever bytes_type or string_type is resolved to. Other solutions would be on library site or simply hacks.
