Filename change in Kobo profiles

[hvmzx]

Hi, I've been encountering this issue where with an input of a file with spaces and hyphens, those are deleted in the output file. For example : "One Piece - Chapter 4.cbz" will be named "OnePieceChapter4.kepub.epub".

This happens with any Kobo profile set as an option, maybe the kepub conversion does this. With a Kindle profile it works well and the filename is preserved (but not kepub).

I don't have a Kobo to test, but looks like intentional behavior. Not sure if spaces and special characters cause issues on older kobos

       if 'Ko' in options.profile and options.format == 'EPUB':
            path = srcpath.split(os.path.sep)
            path[-1] = ''.join(e for e in path[-1].split('.')[0] if e.isalnum()) + tomenumber + ext
            if not path[-1].split('.')[0]:
                path[-1] = 'KCCPlaceholder' + tomenumber + ext
            filename = os.path.sep.join(path)

Looks like this can't be fixed to maintain compatibility with older devices. I don't have a Kobo however and can't confirm.

For compatibility with older reading systems, file names SHOULD NOT contain SPACE (U+0020) characters.

The Kindle case is different since Kindles don't read EPUB natively, it's an intermediate format fed into KindleGen.

I think just removing or replacing special characters is the only option.

Unless we had a list of kobos that are confirmed compatible with spaces...

My Kobo reads .epub files just fine, also no problems with spaces whatsoever. I haven't read anything about kobo's not being able to read files with spaces especially as they run on pretty much the same software.

Where did you see this ?

Looks like this renaming code was added in response to

• #141

However, the discussion doesn't seem to blame the filename for the underlying issue so it might be safe to remove.

Which Kobo do you have?

I own the Kobo Clara HD

Want to create a PR with that code section deleted and testing that it works fine? I really don't see any indication that spaces cause problems on Kobo.
