The easiest solution is the patch below;

-our $fallback = Encode::PERLQQ()|Encode::WARN_ON_ERR();
+our $fallback = 
Encode::PERLQQ()|Encode::WARN_ON_ERR()|Encode::RETURN_ON_ERR();

  1;
  __END__

This makes perl-5.8.6 happy but the problem is that I have made 
Encode::utf8 so that it accepts fallback values like Encode::XS (upon 
the request by Bjoern Hoehrmann via RT).  Encode::utf8 used to return 
immediately at partial character but now Encode:RETURN_ON_ERR is 
required, meaning those who installed Encode-2.07 on older perl are in 
trouble w/ PerlIO.  So I am looking for a solution which does that 
without tweaking PerlIO::encoding.

I just want Encode::utf8->decode() to make sure Encode:RETURN_ON_ERR is 
on when the callar is PerlIO::encoding...
