So now we all understand a little more about how this all ties together.  
Good.  I hate mysteries :-)

It seems I had misunderstood 'fallback'.  My (wrong) logic said that it would 
be used if utf-8 had any problems with the content.  Now I understand its 
purpose I have simply set the fallback to utf-8.  Hopefully all will display 
better for the change :-)

Thanks for taking the time to educate us, Ingo :-)
