The UTF-8 BOM is a sequence of bytes at the start of a text stream (0xEF, 0xBB, 0xBF) that allows the reader to more reliably guess a file as being encoded in UTF-8.
Normally, the BOM is used to signal the endianness of an encoding, but since endianness is irrelevant to UTF-8, the BOM is unnecessary.
According to the Unicode standard, the BOM for UTF-8 files is not recommended:

The BOM is, simply, the Unicode codepoint U+FEFF ZERO WIDTH NO-BREAK SPACE, encoded in the current encoding. A text file beginning with the bytes FE FF suggests that the file is encoded in big-endian UTF-16. The name ZWNBSP should be used if the BOM appears in the middle of a data stream. … See more
