You must differentiate what is the name and path of a file, from its content.
The error says that the name or path of some file inside the zip contains a "special" character.
The messages you get from visual studio code probably refer to the content of a file, which is different from the file name.
You will have to check the names and paths of the files you are trying to upload, once you find it, rename it and make the corresponding corrections within your game code.
