Um, just curious about this, but... what is the point (the purpose, benefit, short-cut or whatever) of passing a hashref to Encode::decode_utf8()?

If you were actually expecting to set the utf8 flags on the keys and values of the hash that is being passed by reference, that would simply be a misconception in your code. (But I gather that was not the intention.)

If it's just a situation that you are doing something with a list of who-knows-what, and you're just passing every element of the list to decode_utf8, regardless of what it might be, well, that seems a bit silly. You didn't show an actual snippet from the application in question, but I think it might be better for you, if your code looks something like this: 

    @olist = map { decode_utf8( $_ ) } @ilist;

to just add a little bit to make it sensible, like this: 
    @olist = map { (ref() ? $_ : decode_utf8( $_ ) } @ilist;

Given what you've said, I'd suggest that you treat the problem as a bug in your app -- functions intended for strings should not be applied to references. (You wouldn't pass a hashref to substr() or index(), would you?)
