Step 1: Determine the UTF-8 encoding bit layout
The character ⪉ has the Unicode code point U+2A89. 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+2A89 to binary:
00101010 10001001. 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 10101010 10001001

Description
The Unicode character U+2A89, known as the LESS-THAN AND NOT APPROXIMATE symbol (≪), is a specialized mathematical sign used primarily in digital text representation. In mathematical notation, it is utilized to express that two given real numbers are not approximately equal, despite being close in value. It serves an important role in contexts where precision and accuracy of numerical values are critical, such as engineering, computer science, and scientific research. This character helps distinguish between numbers that are very close but still not considered to be on the same level of approximation. As part of the Unicode standard, the LESS-THAN AND NOT APPROXIMATE symbol ensures consistency and interoperability across various digital platforms and languages.
