There is no way, Qt or not.

You can try to guess and there are many heuristic algorithms out there 
(most commonly found on web browsers, actually), but none is 100%. You can 
get some high rate, though, but the algorithm may be very complex.

UTF-8 is one quite easy to detect because it's fairly structured. But it's 
also not 100%.
