This is why most properties files end up looking more like this: So, reading UTF-8 as Latin-1 yields seemingly corrupted text as the boundaries for bytes that make upa character are all wrong and when Java once again converts it to UTF-8 (which is how the String class stores its data internally), instead of having access to the raw bytes, the boundaries set by Latin-1 characters are honored and that doesn't help us see any meaningful data either. The reason behind this is that by default Java's Properties class uses an input stream that has Latin-1 encoding.
