In engineering, double-subscript notation is a notation used to indicate some variable between two points (each point being represented by one of the subscripts). In electronics, the notation is usually used to indicate the direction of current or voltage, while in mechanical engineering it is sometimes used to describe the force or stress between two points, and sometimes even a component ...
The most common superscript digits (1, 2, and 3) were included in ISO-8859-1 and were therefore carried over into those code points in the Latin-1 range of Unicode. The remainder were placed along with basic arithmetical symbols, and later some Latin subscripts, in a dedicated block at U+2070 to U+209F.

In LaTeX mathematical mode, the ASCII vertical bar produces a vertical line, and \| creates a double vertical line (a | b \| c is set as | ‖). This has different spacing from \mid and \parallel , which are relational operators : a \mid b \parallel c is set as a ∣ b ∥ c {\displaystyle a\mid b\parallel c} .
These match the LaTeX definitions exactly: please do not modify them for something more "convenient", thank you. Subscript: Enter the subscript (symbol or short expression), for the lower limit or denoting an n-dimensional space or the (n − 1)- dimensional boundary. Superscript: Enter the superscript (symbol or short expression) for the upper ...
Often used for finite fields, with a subscript to indicate the order. [26] Also represents a Hirzebruch surface or a free group, with a subscript to indicate the number of generators (or generating set, if infinite). U+1D53E: 𝔾 Represents a Grassmannian or a group, especially an algebraic group.
Superscripts and Subscripts is a Unicode block containing superscript and subscript numerals, mathematical operators, and letters used in mathematics and phonetics. The use of subscripts and superscripts in Unicode allows any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX.
