Description

The Unicode character U+2021, also known as the DOUBLE DAGGER (⋄), is a typographical symbol that has its origins in early digital text. It represents a symbolic figure of two daggers crossed together. This character has been used to denote a reference to an earlier statement or part of a text, similar to the use of the double asterisk (*) as a footnote indicator. While not as commonly utilized today due to the prevalence of other footnoting and referencing systems, it remains a valuable tool for those who require a distinct visual marker in their digital texts. It is especially useful in cases where an author wishes to draw attention to a specific statement or argument without disrupting the flow of reading with additional symbols or punctuation. The DOUBLE DAGGER's historical use and unique appearance make it a fascinating character in the world of typography and text formatting.

How to type the symbol on Windows

Hold Alt and type 8225 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+2021. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format: 1110xxxx 10xxxxxx 10xxxxxx
    Where the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+2021 to binary: 00100000 00100001. Those are the payload bits.

  3. Step 3: Fill in the bits to match the bit pattern:

    Obtain the final bytes by arranging the paylod bits to match the bit layout:
    11100010 10000000 10100001
