Teletext character set

This article covers technical details of the character encoding system defined by ETS 300 706 of the ETSI, a standard for World System Teletext, and used for the Viewdata and Teletext variants of Videotex in Europe.

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

Control characters
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.

In formats where compatibility with ECMA-48's C0 control codes such as and  is not required, these control codes are sometimes mapped transparently to the Unicode C0 control code range (U+0000 through U+001F). Amongst C1 control code sets, the ITU T.101 C1 control codes for "Serial" Data Syntax 2, are mostly a transposition of the Teletext spacing controls, except for the inclusion of at 0x9B.
