I had seen iconv.  Even if my system supports it and it is faster than 
Python's charmap decoder, it might not be available on other systems.  
Requiring something unusual in order to do a trivial LUT task isn't an 
acceptable solution.  If I write a charmap decoder as an extension 
module in Pyrex I can include it with the program.  I would prefer a 
solution that doesn't even need that, preferably in pure Python.  Since 
Python does all the hard wark so fast it certainly could do it, and it 
can almost do it with "".translate().
