From perlbug@plan9.de

Created by perlbug@plan9.de

This is my first venture into "Encode" land, so I am not accustomed to
Encode, but still I believe that this is a bug.

I tried the following program on debians 5.8.4 perl, as well as my own
(5.8.4-based) perl. The latter has Encode 1.99_01 and Encode​::JP 1.25
(as well as others) installed. The debian perl uses Encode 1.99 and
Encode​::JP 1.25.

  use Encode;

  $test = "xx\x{b0}yy";
  $test = encode "iso-8859-1", $test, 1;

  $prefix = decode "iso-2022-jp", $test, 1;

  warn "prefix is $prefix, test is $test\n";

This outputs​:

  prefix is xx, test is °yy

(the ° is the \x{b0]).

Now, the original string is not valid iso-2022-jp, so I would expect
it to croak as advertised. It behaves as if FB_QUIET were specified,
though. Replacing the decode line with​:

  $prefix = decode "utf-8", $test, 1;

Results in a die​:

  utf8 "\xB0" does not map to Unicode at /opt/perl/lib/perl5/Encode.pm line 164.

So the behaviour is at least inconsistent.
