U+00B1 Plus-Minus Sign
U+00B1 was added in Unicode version 1.1 in 1993. It belongs to the block Latin-1 Supplement in the Basic Multilingual Plane.
This character is a Math Symbol and is commonly used, that is, in no specific script. The character is also known as biquintile (astrological aspect: 144°).
The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it is written as end of a European number, e.g., a currency symbol, from left to right. When changing direction it is not mirrored. U+00B1 prohibits a line break after it, if it is followed by a number.
The CLDR project calls this character “plus-minus” for use in screen reading software.
The Wikipedia has the following information about this codepoint:
The plus–minus sign or plus-or-minus sign, ±, is a symbol with multiple meanings.
- In mathematics, it generally indicates a choice of exactly two possible values, one of which is obtained through addition and the other through subtraction.
- In statistics and experimental sciences, the sign commonly indicates the confidence interval or uncertainty bounding a range of possible errors in a measurement, often the standard deviation or standard error. The sign may also represent an inclusive range of values that a reading might have.
- In chess, the sign indicates a clear advantage for the white player; the complementary minus-plus sign, ∓ indicates the same advantage for the black player.
Other meanings occur in other fields, including medicine, engineering, chemistry, electronics, linguistics, and philosophy.
