I ran the conversion script on this data, and it recognizes that it is not in utf-8 and even produced an output file. However, the output file is still not in utf-8 and the script will not convert them. We think it is due to them containing this character.
This picture shows what the data looks like in it's original encoding: ISO-8859-2

This picture shows what happens when the encoding is changed to utf-8 manually in notepad++
