U+0018 Cancel *
U+0018 was added in Unicode version 1.1 in 1993. It belongs to the block Basic Latin in the Basic Multilingual Plane.
This character is a Control and is commonly used, that is, in no specific script. The character is also known as CANCEL.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Boundary Neutral. When changing direction it is not mirrored. U+0018 prohibits a line break before it.
The Wikipedia has the following information about this codepoint:
In telecommunications and character encoding, the term cancel character refers to a control character which may be either of:
- "CAN", "Cancel", U+0018, or
^Xused to indicate that the data with which it is associated are in error or are to be disregarded. Exact meaning can depend on protocol. For example:
- In some journalistic text transmission formats, it signifies that the preceding word should be deleted; it is sometimes called "Kill Word" ("KW") in this context.
- In some Videotex formats, it stops any running macros. In others, it clears the current line after the cursor position (compare EL).
- "CCH", "Cancel Character", U+0094, or
ESC Tused to erase the previous character. This character was created as an unambiguous alternative to the much more common backspace character ("BS", U+0008), which has a now mostly obsolete alternative function of causing the following character to be superimposed on the preceding one.
