Cannot lookup ISO-8859 NameSpace using Unicode

[whiteknight]

I tried to add this test to t/pmc/namespace.t, but it failed:

    push_eh eh8
    $P0 = get_global [ unicode:"François" ], "baz"
    $I0 = isnull $P0
    is($I0, 0, "Find Sub in an ISO-8859-1 NameSpace looked up by a Unicode name")
    $S0 = $P0()
    say $S0
    is($S0, iso-8859-1:"François", "ISO-8859 NameSpace with Unicode name")
    goto end_test8
  eh8:
    ok(0, "Cannot find ISO-8859 NameSpace using Unicode name")
  end_test8:
    pop_eh

...

.namespace [iso-8859-1:"François"]
.sub 'baz'
    .return(iso-8859-1:"François")
.end

I was under the impression that this should work, that we should be able to compare strings which are using different encodings. Since NameSpace delegates to Hash, I assume Hash has a similar problems (but haven't tested).

As a quick followup note, if I change the NameSpace lookup from this:

$P0 = get_global [ unicode:"François" ], "baz"

To this:

$P0 = get_global [ iso-8859-1:"François" ], "baz"

The tests both pass as expected.
