A character generator, often abbreviated as CG, is a device or software that produces static or animated text (such as news crawls and credits rolls) for keying into a video stream. Modern character generators are computer-based, and they can generate graphics as well as text.
Midnight Commander using box-drawing characters in a terminal emulator. Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes. These characters are characterized by being designed to be connected horizontally and/or vertically with ...
Box Drawing is a Unicode block containing characters for compatibility with legacy graphics standards that contained characters for making bordered charts and tables, i.e. box-drawing characters. Its block name in Unicode 1.0 was Form and Chart Components .
The LED variant is typically manufactured in single or dual character packages, allowing the system designer to choose the number of characters suiting the application.

In Unicode, characters can have a unique name. A character can also have one or more alias names. An alias name can be an abbreviation, a C0 or C1 control name, a correction, an alternate name or a figment. An alias too is unique over all names and aliases, and therefore identifying.
In all braille systems, the braille pattern dots-0 is used to represent a space or the lack of content. [1] In particular some fonts display the character as a fixed-width blank.

These illegal characters are either C0 control characters (the range 0–0x1F), DEL (0x7F), or bytes with the high bit set. Possible responses are to ignore the byte, to process it immediately, and furthermore whether to continue with the CSI sequence, to abort it immediately, or to ignore the rest of it.
