It turns out it's due to the Apache::Table not storing the UTF-8 flag.

if you do the following.

my $foo = $r->param('foo');
$foo = decode('utf-8',$foo); #this sets the utf-8 flag.
my $before = Encode::is_utf8($foo); # $before will be set to 1.
$r->param('foo',[$foo]); #set the param
$foo = $r->param('foo'); #refetch the param
my $after = Encode::is_utf8($foo) # $after will be set to 0.

So everytime you pull a param from $r or use an arg you have to always 
decode.
