U+2021 Double Dagger

U+2021 was added in Unicode version 1.1 in 1993. 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. Znak jest również znany jako diesis i double obelisk.

The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. If its East Asian Width is “narrow”, U+2021 forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.

The CLDR project calls this character “znak podwójnego sztyletu” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: obelisk, obelos, obelus, podwójny, sztylet.

Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

Crux philologorum (łac. krzyż filologów, miejsce męki filologów), inaczej obelos, obelus, obelisk, dagger (pol. sztylet) – znak edytorski mający postać krzyżyka † albo podwójnego krzyża ‡. W języku znaczników HTML uzyskiwane są poprzez odwołania znakowe nazwane &dagger; (†) oraz &Dagger; (‡). W Unikodzie znaki te występują odpowiednio jako U+2020 oraz U+2021.
