You should also consider full-non-ambiguous words before trying with trigrams. "marché" is only available in French, whereas "mar", "arc", ... are available in lots of languages. This should drastically improve your results.

Store only the top N common non-ambiguous words if the RAM consumption matters ;)

Or store the lexicon in a determinisitic acyclic finite state automaton. E.g. (shameless plug):

Though, having implemented a language guesser myself, it's only an issue with very short texts (a few words). On longer texts models based on character n-grams achieve very high accuracies.
