First of all it easier to detect ASCII only then latin1/2 etc ...
Because there are only 127 possible chars (well less because you can
see from 32-127), while in latin1, you will see higher values, but it
will take time to understand why you see the *wrong* chars rather then
the correct ones. At least for :)
