If that is the reason, at least HZ encoding would seem to be affected  
as well.  Explicitly discouraging a more or less random subset of the  
problematic encdodings without providing rationale makes it difficult  
to assess whether or not other, somewhat similar, encodings should be  
avoided as well, which was the main issue I wanted to raise.
