Step 1: Determine the UTF-8 encoding bit layout
The character ⑧ has the Unicode code point U+2467. 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+2467 to binary:
00100100 01100111
. 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 10010001 10100111

Description
The Unicode character U+2467 is known as the "Circled Digit Eight." It is part of the "Circled Numbers" category in the Unicode Standard, which consists of characters representing digits enclosed within a circle. These circled numbers are primarily used to distinguish numeric characters when they appear in uppercase forms or to differentiate them from other similar symbols. The U+2467 character is often employed in mathematical equations and scientific notations to convey the value eight, while ensuring its distinction from other characters like the letter O or zero. Its usage is predominantly found in computerized typesetting, where it helps avoid confusion with other characters that share a similar appearance but hold different meanings.
