Unicode错误PyPdf

Question

我尝试使用requests库下载多个pdf，并使用pypdf将它们合并在一起。一般来说，这工作正常，但对于一些PDF，我只是得到一个错误。

MWE.py

import requests 
from pyPdf import PdfFileWriter, PdfFileReader 
from StringIO import StringIO 


input = PdfFileReader(StringIO(response.content)) 
input.decrypt("") 
output = PdfFileWriter() 
output.addPage(input.getPage(0)) 

outputStream = file("document-output.pdf", "wb") 
output.write(outputStream) 
outputStream.close() 

session.close() 

错误

Traceback (most recent call last): 
    File "mwe.py", line 21, in <module> 
    input.decrypt("") 
    File "/usr/local/lib/python2.7/dist-packages/pyPdf/pdf.py", line 894, in decrypt 
    return self._decrypt(password) 
    File "/usr/local/lib/python2.7/dist-packages/pyPdf/pdf.py", line 904, in _decrypt 
    user_password, key = self._authenticateUserPassword(password) 
    File "/usr/local/lib/python2.7/dist-packages/pyPdf/pdf.py", line 945, in _authenticateUserPassword 
    encrypt.get("/EncryptMetadata", BooleanObject(False)).getObject()) 
    File "/usr/local/lib/python2.7/dist-packages/pyPdf/pdf.py", line 1818, in _alg35 
    key = _alg32(password, rev, keylen, owner_entry, p_entry, id1_entry) 
    File "/usr/local/lib/python2.7/dist-packages/pyPdf/pdf.py", line 1729, in _alg32 
    m.update(id1_entry) 
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128) 

对于跟踪我从文件中读取输入，但我不认为它在这种情况下很重要。

我发现这个问题有一些相关的问题，但我无法解决我的具体问题。

好吧，我发现，这似乎是内部pyPdf（1.13） https://github.com/mstamy2/PyPDF2/issues/51

使用PyPDF2（1.26.0）中的错误，而不是作为工作到目前为止预期。
