Daniel Dardailler on August 18, 1999 suggested:
A (somewhat costly) repair technique for guessing the primary LANG is the use of dictionaries of common and exclusive words in common languages. E.g. is you find "a, the, you, for, is, of, and" then it's engligh, if you find "le, du, la, a, se, pour, aux, des, ne" then it's french, etc.
