Step 1: Determine the UTF-8 encoding bit layout
The character ⥻ has the Unicode code point U+297B. 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+297B to binary:
00101001 01111011. 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 10100101 10111011

Description
The Unicode character U+297B, known as the Superset Above Leftwards Arrow, is a mathematical symbol used in digital text to represent the concept of a leftwards arrow that indicates the superset relationship between two sets. This particular glyph has important applications within various fields, including computer science, mathematics, and engineering. It is primarily utilized in set theory, where it helps to visually illustrate the hierarchy between different sets, demonstrating which set contains or "supersets" another. This can be especially useful when explaining complex concepts, such as inclusions and disjointness in abstract algebra, or when representing various levels of classification in data organization. Despite its niche application, this symbol is integral to precise communication in certain disciplines and ensures that information is accurately conveyed without ambiguity.
