Teletext character set


This article covers technical details of the character encoding system defined by ETS 300 706, 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, character height, current default character set, and other attributes.
These C0 control codes mostly correspond to a transposition of the ITU T.101 C1 control codes for "Serial" Data Syntax 2, except for the inclusion of ESC at 0x1B instead of CSI.
