U+20E7 Combining Annuity Symbol

U+20E7 wurde in Version 3.2 in 2002 zu Unicode hinzugefügt. Er gehört zum Block U+20D0 bis U+20FF Combining Diacritical Marks for Symbols in der U+0000 bis U+FFFF Basic Multilingual Plane.

Dieses Zeichen ist ein Nonspacing Mark und erbt seine Schrift-Eigenschaft vom vorhergehenden Zeichen. Das Schriftzeichen ist auch bekannt als actuarial bend.

Das Zeichen ist keine Zusammensetzung. Es hat keine zugewiesene Weite in ostasiatischen Texten. In bidirektionalem Text handelt es als Nonspacing Mark. Bei einem Richtungswechsel wird es nicht gespiegelt. U+20E7 verbietet einen Zeilenumbruch vor sich.

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

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.
