// GENERIC
// A, E, I, O, P, U should create variants, but a, e, i, o, u should not create any new variant
// Q = ü ; Y = ä = ö
// EE = final "e" (english or french)

// VOWELS
    // "ALL" DIPHTHONGS are interchangeable BETWEEN THEM and with monophthongs of which they are composed ("D" means "diphthong")
    //  {a,o} are totally interchangeable if non-stressed; in German "a/o" can actually be from "ä/ö" (that are equivalent to "e")
    //  {i,e} are interchangeable if non-stressed, while in German "u" can actually be from "ü" (that is equivalent to "i")
