UTF-8 is a byte sequence, so it's not about the first byte in the whole
sequence. But about the first byte in a tree byte sequece.

There should be no nul (0) bytes when encoding UTF-8. I believe this is in the
specification to allow it to be compatible with C nul-terminated strings.

I believe that the byte sequence 0x00EF i illegal UTF-8 because:
1) It contains nul (0x00) byte
2) 0xEF is not followed by two more bytes

On the other hand U+00EF is a valid unicode code point. Which points to:
LATIN SMALL LETTER I WITH DIAERESIS
It is encoded as 0xC3AF in UTF-8
As 0x00EF in UTF-16 (and UCS-2 ?)
As 0xEF in ISO-8859-1
