U+2051 Two Asterisks Aligned Vertically

U+2051 was added in Unicode version 3.2 in 2002. It belongs to the block U+2000 to U+206F General Punctuation in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Punctuation and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+2051 forms with similar adjacent characters prevents a line break inside it.

Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

The asterisk ( *), from Late Latin asteriscus, from Ancient Greek ἀστερίσκος, asteriskos, "little star", is a typographical symbol. It is so called because it resembles a conventional image of a heraldic star.

Computer scientists and mathematicians often vocalize it as star (as, for example, in the A* search algorithm or C*-algebra). An asterisk is usually five- or six-pointed in print and six- or eight-pointed when handwritten, though more complex forms exist. Its most common use is to call out a footnote. It is also often used to censor offensive words.

In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, or multiplication.
