 The first one. For the second one, 0x000003 000000 05 has an illegal
                                             ^^^^^^
sequence of bytes.
  The standard is a bit confusing on this subject:
"[...]
 and a byte equal to 0x03 is inserted to replace these bit patterns with
the patterns
'00000000 00000000 00000011 000000xx',
[...]"
But it does not make clear is that 000000xx takes part in the next
0x000000
sequence if it is present.
