Errors if file name contains escaped special characters (space, parenthesis etc)

Am I wrong or is your filename containing spaces?
I think this could be the cause of your problems.

Hi Narnie!

Your problem could be related to this other bug, for which I found a patch (working for my case).
Could you please check if this solves also your case?

If not, could you provide the CHM file causing the problem?

Kind regards!

I searched and found the file "Python In A Nutshell, 2nd Edition (2006).chm" and tryied following:

- renaming the file so that it doesn't contains any special character like spaces or parenthesis, it converts well
- escaping the spaces in name of the file is not enough as also () need to be escaped (bash: syntax error near unexpected token '(' )
- escaping also ( and ) will give me exacly the situation reported by narnie.
- installing the patch of bug 894193 won't correct this

In the code, we have situatiuons like those:
        # the python interpreter handles files with spaces just fine, so we have to unescape
        # our spaces when passing files as arguments to library functions
        if os.path.exists(re.sub('\\\\ ', ' ', page_filename)) and (options['titlefile'] == '' or not options['titlefile'] in url):

And those will only catch escaped spaces, not other escaped special characters like ( or )

I made this CHM file to test....
- contains spaces, ( and ) in the name of the file
- contains spaces, ( and ) also in the paths and names of htm pages

I tried to solve the problem, mostly using re.escape() instead using re.sub(' ', '\ ',
See the diff file for details....

Yet another way to solve the problem is quote ('') the filename.
