Using Java on Android I'm struggling to convert a couple of html special characters. 

So far I've tried:

```
String myString = "%A32.00%20per%20month%B3";

Html.fromHtml(myString).toString(); => %A32.00%20per%20month%B3
URLDecoder.decode(myString) => �2.00 per month�
URLDecoder.decode(myString, "UTF-8") => �2.00 per month�
URLDecoder.decode(myString, "ASCII") => �2.00 per month�
org.apache.commons.lang.StringEscapeUtils.unescapeHtml4(myString) => %A32.00%20per%20month%B3

```

The correct output should be => £2.00 per month³
