描述

test2.zip The uploaded file is a test compression file. You can reproduce the same phenomenon with these files. If you go to the actual cache folder, you can see that two image files are missing. There seems to be a person who has similar symptoms on the discord channel. Originally, it was right to attach a log, but I couldn't upload it because there was no record in the log.

Tested at version 0.7.7 and docker environment. Host os is ubuntu 22.04 The client environment is windows 11 22H2 I tested with the latest version of Chrome and Edge.

研究方向
Investigate how Kavita extracts files from compressed archives (likely using a library like SharpCompress or similar). Look for code that handles file names, particularly non ASCII or numeric filenames. Check if there is any encoding conversion or sanitization. Review the extracted file path generation to ensure it can handle different character sets. The provided test zip can be used to reproduce the issue.
