Encoding iso-8859-16

Hi

I am running the following script on EBCDIC 

use Encode;
$string = "a";
$enc_string = encode("iso-8859-16", $string);
print "\n String: $string\n";
print "\n enc_string: $enc_string\n";


The output:

String: a
enc_string: ñ (This is the character for codepoint \xF1 on iso-8859-16)

What is the expected output in enc_string?

On Linux both String and enc_string are set to "a"

Thanks in advance

regards
