U+20E7 Combining Annuity Symbol

U+20E7 was added in Unicode version 3.2 in 2002. It belongs to the block U+20D0 to U+20FF Combining Diacritical Marks for Symbols in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Nonspacing Mark and inherits its script property from the preceding character. Znak jest również znany jako actuarial bend.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Nonspacing Mark. When changing direction it is not mirrored. U+20E7 prohibits a line break before it.

Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

Actuarial notation is a shorthand method to allow actuaries to record mathematical formulas that deal with interest rates and life tables.
Traditional notation uses a halo system, where symbols are placed as superscript or subscript before or after the main letter. Example notation using the halo system can be seen below.
Various proposals have been made to adopt a linear system, where all the notation would be on a single line without the use of superscripts or subscripts. Such a method would be useful for computing where representation of the halo system can be extremely difficult. However, a standard linear system has yet to emerge.
