Formally, yes, it's wrong. But the use of U+FEFF as zero width
no-break space is deprecated since almost ten years, and the
overwhelmingly vast majority of use cases of that character will be as
"BOM" -- more correctly, as Unicode encoding scheme marker, since byte
order is not an issue for UTF-8, as I'm sure you know.
I realize this does not help in making a decision, I only wanted to
answer Karl's question as precisely as possible.
