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
to0xffff
.
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 thex
are the payload bits.UTF-8 Encoding bit layout by codepoint range Codepoint Range Bytes Bit pattern Payload length U+0000 - U+007F 1 0xxxxxxx 7 bits U+0080 - U+07FF 2 110xxxxx 10xxxxxx 11 bits U+0800 - U+FFFF 3 1110xxxx 10xxxxxx 10xxxxxx 16 bits U+10000 - U+10FFFF 4 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 21 bits Step 2: Obtain the payload bits:
Convert the hexadecimal code point U+2021 to binary:
00100000 00100001
. Those are the payload bits.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

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.
