Step 1: Determine the UTF-8 encoding bit layout
The character ≑ has the Unicode code point U+2251. 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+2251 to binary:
00100010 01010001. 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 10010001

Description
U+2251, known as the "GEOMETRICALLY EQUAL TO" character, is a symbol used in mathematical expressions to indicate equality in terms of shape rather than numerical value. Its primary role is within digital text, particularly in fields such as geometry, where it helps clarify that two shapes or figures are equivalent in form despite differences in size or positioning. This unique symbol holds importance in various areas of study including architecture, art history, and design, where the focus is on the visual aesthetics rather than numerical properties. Its usage underscores the versatility of Unicode characters in representing a wide range of concepts beyond simple alphanumeric values.
