U+0602 Arabic Footnote Marker

U+0602 was added in Unicode version 4.0 in 2003. It belongs to the block U+0600 to U+06FF Arabic in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Format and is mainly used in the Arabic script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written as Arabic number from right to left. When changing direction it is not mirrored. This number joins with other adjacent letters and numbers to form a word. U+0602 forms a number with similar characters, which prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

A note is a string of text placed at the bottom of a page in a book or document or at the end of a chapter, volume, or the whole text. The note can provide an author's comments on the main text or citations of reference work in support of the text.
Footnotes are notes at the foot of the page while endnotes are collected under a separate heading at the end of a chapter, volume, or entire work. Unlike footnotes, endnotes have the advantage of not affecting the layout of the main text, but may cause inconvenience to readers who have to move back and forth between the main text and the endnotes.
In some editions of the Bible, notes are placed in a narrow column in the middle of each page between two columns of biblical text.
