A teletext decoder has a character memory comprising a common language set of characters and a plurality of sub-sets of national option characters, each of which latter sets makes up a complete national language set when combined with the common language set. The totality of characters are addressable using n bit digital codes together with an additional bit which determines one of two addressing modes. In one addressing mode, only one of the national option sub-sets can be selected by addressing means so that a page can be displayed using one complete language set. In the other addressing mode, all the national option sub-sets can be selected by processor means to enable a page to be displayed using more than one language set.
