Step 1: Determine the UTF-8 encoding bit layout
The character ≔ has the Unicode code point U+2254. 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+2254 to binary:
00100010 01010100. 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 10001001 10010100

Description
The Unicode character U+2254, known as the COLON EQUALS (∶), is a mathematical symbol that primarily finds application in digital text within the realm of mathematics and related disciplines. It serves to denote the equality between two expressions in an organized format. Although it is not widely utilized in everyday language, its usage can be found in specific contexts such as mathematical equations, programming languages, and other fields where precise expression of relationships is crucial. The COLON EQUALS symbol is part of the Mathematical Operators block within the Unicode Standard, which comprises a comprehensive collection of characters used for encoding text across various languages and scripts. While it may not be commonplace in everyday usage, the COLON EQUALS serves an important purpose in specialized fields where precise expression of relationships is essential.
