The human algorithm is approximately:

if HangulPresent ==> Korean
elif KanaPresent ==> Japanese
elif SimplifiedCharactersPresent ==> Chinese (simplified)
elif ChineseCharacterNotInJapanesePresent ==> Chinese (traditional)
else SearchForWordsIRecognizeInText.

No doubt a number of people have done a table- and range-based simple
version of the first four steps that ought to provide a 99+% accurate
heuristic based on a single line of text.
