Can you verify if this fixes your issue?

Various characters are illegal in older EPUB readers, including spaces. https://www.w3.org/TR/epub-33/#sec-container-filenames

Code based on: https://stackoverflow.com/questions/12985456/replace-all-non-alphanumeric-characters-in-a-string

Before and after:

I do not have a kobo to test so there's no way for me to verify if this build causes other issues.

Just checked, this is what I get with the input : Oda Eiichiro - One Piece - Chapter 1053 The New Emperors.cbz

python3 kcc-c2e.py -p KoC -m -u -s -d -f EPUB -> Oda_Eiichiro_One_Piece_Chapter_1053_The_New_Emperors.kepub.epub
python3 kcc-c2e.py -p K -m -u -s -d -f KV EPUB -> Oda Eiichiro - One Piece - Chapter 1053 The New Emperors.epub

Both are considered epubs, yet the Kindle profile has spaces but the Kobo one is handled differently with "_" instead.

Also, I find the author/creator set to KCC in the metadata, is there option to bypass that ? Because it later on messes up the metadata and puts every manga under the author KCC. Or if there is a way to set the metadata based on the filename ? Like AUTHOR - TITLE - Volume.epub and those parameters are parsed and filled up in the metadata.
