Hi Dingo/All,
 
Recently I have been getting strange characters in e-mail sent 
by Dingo (no one else). Please see the example below. From the context, it 
usually seems to show up in place of an apostrophe. Also, a couple of times, I 
got a message that I need to download Japanese character set to read Dingo's 
mail. Any idea why Dingo? Anyone else? Thanks very much!
 
Steve

  Regardless of what any particular system returns or doesn't I would want to
