Step 1: Determine the UTF-8 encoding bit layout
The character ⟟ has the Unicode code point U+27DF. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800to0xffff.
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 thexare 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+27DF to binary:
00100111 11011111. 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 10011111 10011111

Description
The Unicode character U+27DF, known as the "UP TACK WITH CIRCLE ABOVE," is a typographical symbol primarily used in digital text for representing an upward arrow enclosed within a circle. In its most common usage, it serves as an indicator in mathematical equations or logical expressions to denote upward movement or elevation. Although not widely used in everyday language, the UP TACK WITH CIRCLE ABOVE holds significant importance in certain technical and scientific contexts, particularly in fields such as computer programming, engineering, and advanced mathematics. Its unique combination of an arrowhead and a circle provides a visually distinct symbol that can be easily recognized and interpreted by readers familiar with its specific meaning.
