Step 1: Determine the UTF-8 encoding bit layout
The character ≡ has the Unicode code point U+2261. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+2261 to binary:
00100010 01100001
. 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 10100001

Description
The Unicode character U+2261 is known as the "IDENTICAL TO" symbol. This mathematical symbol represents an equivalence relation, indicating that two objects are identical. It is used in digital text primarily within the field of mathematics, particularly in algebra and set theory, to express a relationship between two elements where they have the same value or properties. The character can also be found in programming languages and software applications where it serves as a comparison operator to check if two values are equal. Despite being less common, U+2261 may also appear in linguistic contexts, such as in the transcription of non-Latin scripts, to signify phonetic identity between words or phrases. While not widely recognized outside of specialized domains, the "IDENTICAL TO" symbol plays a crucial role in ensuring accuracy and precision within its specific areas of application.
