Step 1: Determine the UTF-8 encoding bit layout
The character ⩰ has the Unicode code point U+2A70. 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+2A70 to binary:
00101010 01110000. 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 10101001 10110000

Description
The Unicode character U+2A70, known as "APPROXIMATELY EQUAL OR EQUAL TO" (≉), is a typographical symbol that holds significant importance in mathematical equations, specifically within the domain of physics and engineering. This symbol, represented by ≉, is primarily used to depict an approximation or equivalence between two quantities or values that are not precisely equal, but close enough for practical purposes. Although it is a less commonly used symbol compared to others such as "≈" or "=", its unique representation sets it apart and adds value in specific contexts where a distinction needs to be made between exact equality and approximate parity. In digital text, the U+2A70 symbol is particularly useful when discussing physical quantities that have errors due to measurement limitations, rounding, or computational approximations.
