[SOLVED] Extract files with invalid characters in filename with Python

Extract files with invalid characters in filename with Python

I use python's zipfile module to extract a .zip archive (Let's take this file at http://img.dafont.com/dl/?f=akvaleir for example.)

f = zipfile.ZipFile('akvaleir.zip', 'r')
for fileinfo in f.infolist():
    print fileinfo.filename
    f.extract(fileinfo, '.')

Its output:

Akval�ir_Normal_v2007.ttf
Akval�ir, La police - The Font - Fr - En.pdf

Both files are unaccessable after extraction because there are invalid encoded characters in their filenames. The problem is zipfile module doesn't have an option to specify output filenames.

However, "unzip akvaleir.zip" escapes the filename well:

root@host:~# unzip akvaleir.zip 
Archive:  akvaleir.zip
  inflating: AkvalВir_Normal_v2007.ttf  
  inflating: AkvalВir, La police - The Font - Fr - En.pdf

I tried capturing output of "unzip -l akvaleir.zip" in my python program and these two filenames are:

Akval\xd0\x92ir_Normal_v2007.ttf
Akval\xd0\x92ir, La police - The Font - Fr - En.pdf

How can I get the correct filename like what unzip command does without capturing output of "unzip -l akvaleir.zip"?

Solution

Instead of the extract method, use the open method and save the resulting pseudofile to disk under whatever name you wish, for example with shutil.copyfileobj.
