Step 1: Determine the UTF-8 encoding bit layout
The character ≉ has the Unicode code point U+2249. 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+2249 to binary:
00100010 01001001. 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 10001001

Description
The Unicode character U+2249, known as "Not Almost Equal To," is a mathematical symbol used to denote an inequality that is not almost equal to another value. This symbol plays a vital role in digital text, particularly within the context of mathematics and computer programming, where it helps convey complex relationships between variables and values. The character's significance extends beyond technical applications, as it has been adopted by various programming languages and software tools for its precise representation of the concept of inequality. Notably, U+2249 is part of the broader Unicode Standard, which aims to ensure global compatibility and interoperability in digital text, making it an essential tool for facilitating communication across different languages and cultures.
