This article is about the character sets defined by ETS 300 706. For an overview of the background and history of ETS 300 706, seeWorld System Teletext. For the character sets defined by ITU T.101, seeVideotex character set. For the character sets defined by ITU T.51, seeT.51/ISO/IEC 6937.

This article covers technical details of thecharacter encoding system defined by ETS 300 706 of theETSI, a standard forWorld System Teletext, and used for theViewdata andTeletext variants ofVideotex in Europe.

Character sets

[edit]

The following tables show various Teletext character sets. Each character is shown with a potentialUnicode equivalent if available. Space and control characters are represented by the abbreviations for their names.

Control characters

[edit]

Control characters are used to set foreground and background color (black, red, green, yellow, blue, magenta, cyan, white, flash), character height (normal, double width, double height, double), current default character set, and other attributes.[1][2]

In formats where compatibility withECMA-48'sC0 control codes such asTAB andLF is not required, these control codes are sometimes mapped transparently to the Unicode C0 control code range (U+0000 through U+001F).[3] Amongst C1 control code sets, theITU T.101 C1 control codes for "Serial" Data Syntax 2,[4] are mostly a transposition of the Teletext spacing controls, except for the inclusion ofCSI at 0x9B.

  1. ^The ETS 300 706 name of this control code is "Contiguous Mosaic Graphics", and it switches mosaic characters to contiguous (connected) display.[2] Its other name of "Stop Lining" arises from other formats, as well as using it to switch mosaic characters to connected display, also using it to switch alphanumeric characters to non-underlined display.[4]
  2. ^The ETS 300 706 name of this control code is "Separated Mosaic Graphics", and it switches mosaic characters to separated display.[2] Its other name of "Start Lining" arises from other formats, as well as using it to switch mosaic characters to separated display, also using it to switch alphanumeric characters to underlined display.[4]
  3. ^ESC is also given the alternative name of "Switch" by ETS 300 706. It is used in certain contexts as a toggle between two G0 sets previously designated by dedicated packets.[2]
