You don't. You can try to load with several different codecs and check which 
one works best. Also note that there may be several codecs that load without 
errors. There are many heuristic algorithms for detecting, with varying 
success rates.

My recommendation is that you don't ask this question. Instead, your code 
should know the codec before you open the file. Either that information is 
saved somewhere else, like out-of-band information, or you know the file is 
encoded in the locale codec or it is enforced to be UTF-8.
