I haven't done much research into this, but in general, I think it's
better to:

  * first try to look at other characteristics of a text
    message, e.g. language, origin, topic, etc.,

  * then narrow down the number of encodings which could apply,

  * rank them to try to avoid ambiguities and

  * then try to see what percentage of the text you can decode using
    each of the encodings in reverse ranking order (ie. more specialized
    encodings should be tested first, latin-1 last).
