Let me slightly restate/enhance my other answer:

  a) there are two issues: how a flag is used, and the informal
     meaning we assign to this flag.  The second should not contradict
     the first;

  b) The way the flag is currently used:

      1) during operations which require bytes;
      2) during operations which require utf8;
      3) to chose a branch in polymorphic operations;

     For operations 2) and 3) "my" and "yours" meanings do not
     contradict the usage.  For 1) - as far as I understand, the only
     operation which behaves as "1" is one type of pack().
