"BOM" == UTF-8 Byte Order Mark I guess.
I initially thought it was searching for "Bill of Materials" for electronics projects or similar.

> In UTF-8, the BOM corresponds to the byte sequence <EF BB BF>. Although there are never any questions of byte order with UTF-8 text, this sequence can serve as signature for UTF-8 encoded text where the character set is unmarked. As with a BOM in UTF-16, this sequence of bytes will be extremely rare at the beginning of text files in other character encodings. For example, in systems that employ Microsoft Windows ANSI Code Page1252, <EF16 BB16 BF16> corresponds to the sequence <i diaeresis, guillemet, inverted question mark> “ï » ¿”.
In practice, the UTF-8 BOM pops up. I usually see it on Windows.

That was a fun, and totally unstressful way to begin my time managing a racing league's race events.
Well require is a bit excessive, but it certainly allows and recommends one.
Utf8 does not need one because the code units are bytes, so bytes order is not a concern.
Exchanging utf32 is pretty rare though, and as long as you don’t move anything between machines bytes order is not an issue.
