Foreign letters. Letters must be valid in the language being spoken. For example, “ж” is a letter in the Russian alphabet but is never used in English and so should never appear in any English source text.
Daşary ýurt harplary. Harplar geplenilýän dil üçin dogry bolmaly. Mysal üçin, “ж” rus elipbiýindäki harpdyr, ýöne hiç wagt iňlis dilinde ulanylmaýar we şonuň üçin hiç haçan iňlis dilindäki tekstde görkezilmeli däldir.
