What's different between UTF-8 and UTF-8 without BOM?

Short answer: In UTF-8, a BOM is encoded as the bytes EF BB BF at the beginning of the file.

Long answer:
Originally, it was expected that Unicode would be encoded in UTF-16/UCS-2. The BOM was designed for this encoding form. When you have 2-byte code units, it's necessary to indicate which order those two bytes are in, and a common convention for doing this is to include the character U+FEFF as a "Byte Order Mark" at the beginning of the data. The character U+FFFE is permanently unassigned so that its presence can be used to detect the wrong byte order.
UTF-8 has the same byte order regardless of platform endianness, so a byte order mark isn't needed. However, it may occur (as the byte sequence EF BB FF) in data that was converted to UTF-8 from UTF-16, or as a "signature" to indicate that the data is UTF-8.
