PyPDF2 编码问题 PyPDF2.utils.PdfReadError Illegal character in Name Object
参考资料：https://github.com/mstamy2/PyPDF2/issues/438
使用 PyPDF2 做合并 PDF 文件时报错如下：
Traceback (most recent call last):
File "D:\projects\myproject\venv\lib\site-packages\PyPDF2\generic.py", line 484, in readFromStream
return NameObject(name.decode(‘utf-8‘))
UnicodeDecodeError: ‘utf-8‘ codec can‘t decode byte 0xcb in position 8: invalid continuation byte
During handling of the above exception, another exception occurred:

PyPDF2.utils.PdfReadError: Illegal character in Name Object
找到对应的报错文件
File "D:\projects\myproject\venv\lib\site-packages\PyPDF2\generic.py", line 484
第484行 原代码：
try: return NameObject(name.decode(‘utf-8‘)) except (UnicodeEncodeError, UnicodeDecodeError) as e: # Name objects should represent irregular characters # with a ‘#‘ followed by the symbol‘s hex number if not pdf.strict: warnings.warn("Illegal character in Name Object", utils.PdfReadWarning) return NameObject(name) else: raise utils.PdfReadError("Illegal character in Name Object")
在 except 中加入代码
return NameObject(name.decode(‘gbk‘))
修改后
try: return NameObject(name.decode(‘utf-8‘)) except (UnicodeEncodeError, UnicodeDecodeError) as e: try: return NameObject(name.decode(‘gbk‘)) except (UnicodeEncodeError, UnicodeDecodeError) as e: # Name objects should represent irregular characters # with a ‘#‘ followed by the symbol‘s hex number if not pdf.strict: warnings.warn("Illegal character in Name Object", utils.PdfReadWarning) return NameObject(name) else: raise utils.PdfReadError("Illegal character in Name Object")
修改后仍会报错，需要修改修改另一处
Lib/site-packages/PyPDF2/utils.py 第238行
原代码
r = s.encode(‘latin-1‘) if len(s) < 2: bc[s] = r return r
修改后代码：
try: r = s.encode(‘latin-1‘) except Exception as e: r = s.encode(‘utf-8‘) if len(s) < 2: bc[s] = r return r
