This is for cyrilic mongolian, not for traditionnal mongol (mongol bichig, uyghur mongolian, white head...) Il s'agit de mongol cyrillique, pas de mongol traditionnel (mongol bichig, mongol ouïghour, tête blanche...) For Mongolian, I made an ibus-table-mongol-bichig method, included in ibus-table-others since v1.3.12.
