It's not clear that 404 disallows it, since 404 is defined in terms of
characters, and a BOM is not a character but an out-of-band signal.
However, for example, a conforming implementation of the ECMAScript
JSON.parse function would reject any string passed to it that starts with a
U+FFEF code point because the unquoted occurrence of that code point does not
conform to the ECMA-252, 5th Edition or Ecma-404 JSON grammar.
In order to be successfully processed, that code point would have to be
stripped from the string prior to calling JSON.parse.
The question was specifically about ECMA-404, not ECMA-252. It would be great
to hear from TC39 whether or not ECMA-404 allows or disallows it.
