Additional context
I suspect this issue might occur when adding <link rel="preload" as="image" /> during build time, where Unicode characters aren't being handled properly.
If an image doesn't meet the conditions for preload, it won't be added to <head> and won't cause error output.
I also noticed that no matter how many images with Unicode characters exist on the page, the error is only output once per visit.
