May be it is easier to move this into an own function, like remove_utf8_bom() ?

Do we really need to cast here (and if, is the cast dropping the "const" ?)
Another suggestion, see below:
either:
static const size_t bom_len = 3;
or
static const size_t bom_len = strlen(utf8_bom);

And now we can avoid magic numbers:
if (size >= bom_len && !memcmp(buf, utf8_bom, bom_len))
entry = buf + bom_len;
else
entry = buf;
