You can convert the UTF-8 bytes to Unicode as shown below by the pseudo code. The compare it as a string in Java and replace with empty string.

byte[] utf8 = <whatever data is>
// Convert from UTF-8 to Unicode
string = new String(utf8, "UTF-8");

Hope this helps.
It is sorta covered in the JavaRanch Style Guide.
