I've been having some trouble with a certain web API from a certain large online marketplace site... They are returning multiple results that seem to be the same just different iterations of applying utf8 encoding to the same string. Ex: 
Some Companyî
Some CompanyÃÂÃÂÃÂÃÂÃÂÃÂÃÂî 
Some CompanyÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂî

I'm pretty sure the intention in this example is the ® symbol - a registered trademark type symbol. Somehow on the companies end this data is getting screwed up, and they are apparently working on it - though that might mean a few months of no fix, and I have historical data that I need to use in the mean time. What I'm looking for is an equivalent way to do what the "utf8_decode" function in PHP does, but in Perl. A simple example in PHP would be something like this, that does what I want: 
$prev = $value;
for($i=0;$i<999;$i++) {
    $value = utf8_decode($value);
    if ($prev == $value) {
        break;
    }
    $prev = $value;
    print "[$i]$value\n";
}

I've been trying to get Encode::encode and Encode::decode to work here, but they don't seem to be able to actually unravel this mess. With my PHP hack script I can decode it to this: 
Some Companyî
[0]Some Company®
[1]Some Company®
------------------
Some CompanyÃÂÃÂÃÂÃÂÃÂÃÂÃÂî 
[0]Some CompanyÃÂÃÂÃÂî 
[1]Some CompanyÃÂî 
[2]Some Companyî 
[3]Some Company® 
[4]Some Company® 
------------------
Some CompanyÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂî 
[0]Some CompanyÃÂÃÂÃÂÃÂÃÂÃÂÃÂî 
[1]Some CompanyÃÂÃÂÃÂî 
[2]Some CompanyÃÂî 
[3]Some Companyî 
[4]Some Company® 
[5]Some Company®

I would probably then want to re-encode the final one back into utf8 and proceed from there. I know this is very hacky, but I need a workaround until they fix the data source. Any ideas?
