To quote the zvbi documentation btw:

/* Teletext uses a 7 bit character set. To support multiple
  * languages there are eight national variants which replace
  * the square bracket, backslash and other characters in a
  * fashion similar to ISO 646. These national variants are
  * selected by a 3 bit code in the header of each Teletext page.
  * Eventually eight character sets proved to be insufficient,
  * so manufacturers of Teletext decoders interpreted these bits
  * differently in certain countries or regions. Teletext Level
  * 1.5 finally defined a method to transmit an 8 bit character
  * code which applies to a single page or provides the upper 5
  * bits of the character code for all pages.
  * Regrettably some networks still only transmit the lower 3
  * bits. With this function you can supply an 8 bit default
  * character code for all pages. The built-in default is 16.
