[Plugin: Global Translator] Bad codepage in translations

Hello my web http://fatbozz.towerofglass.net/v2/ is using Global translator. I recently learned that the code page is displayed incorrectly. But I do not know how to fix this error. For example see http://fatbozz.towerofglass.net/v2/lt/garmin-mapy/ in native language seem to be OK.
