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
[edit ]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
[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 with ECMA-48's C0 control codes such as TAB and LF 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, the ITU T.101 C1 control codes for "Serial" Data Syntax 2,[4] are mostly a transposition of the Teletext spacing controls, except for the inclusion of CSI at 0x9B.
Teletext spacing attributes[2]- ^ 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]
- ^ 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]
- ^ 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]
