NICE example for ambiguity of UTF-16 if you don't get the start right!!!

For clarification: your point is that "\xFA" (first block) and "\xDD" (second block) should raise errors?

use warnings;
use strict;
use Encode qw/decode/;
use Data::Dump qw/dd/;


dd decode('UTF-16-BE', "\x3D\xDD\xFA", Encode::FB_CROAK|Encode::LEAVE_
+SRC );
dd decode('UTF-16-BE', "\xFA",         Encode::FB_CROAK|Encode::LEAVE_
+SRC );

dd decode('UTF-16-LE', "\xD8\xFA\xDD", Encode::FB_CROAK|Encode::LEAVE_
+SRC );
dd decode('UTF-16-LE', "\xDD",         Encode::FB_CROAK|Encode::LEAVE_
+SRC);

__END__

"\x{3DDD}"
""
"\x{FAD8}"
""

I agree, looks like a bug we should report.

A really strange one too ...

> Personally I'd just make a version for UTF-8 and UTF-16, and any others as needed, or other encodings can be converted to the supported ones.

I don't even know other wide encodings except unicode , so I prefer relying on Encode for utf8 and make sure utf16 are read modulo 4 bytes 2 bytes.

update

From the docs

    As of version 2.12, "Encode" supports coderef values for "CHECK"; 
+see
    below.

    NOTE: Not all encodings support this feature. Some encodings ignor
+e the
    *CHECK* argument. For example, Encode::Unicode ignores *CHECK* and
+ it
    always croaks on error.

... but it doesn't croak
