Can't read files with certain symbols in filename

Bug/Feature description

Originally I was having an error where cozy couldn't read a file, even though it had access to it and it showed up in the library scan. However, it turns out this is an issue with it being unable to read files that have certain symbols in the $PATH, e.g. #.

Ideally it would be able to read files with these symbols. Or at the very least some error should be thrown to denote that the folder/filename has unsupported characters. Before I found out that it was the issue, I was just getting error messages saying unable to read resource and for me to manually locate the file - which was less clear since it showed up in the library scan, which made me think the folder/filename should be okay.

Steps to reproduce

Add a symbol like # to the folder or filename.
Update library via scan.
Try to play file.
