Step 1: Determine the UTF-8 encoding bit layout
The character ∈ has the Unicode code point U+2208. 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+2208 to binary:
00100010 00001000
. 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 10001000 10001000

Description
The Unicode character U+2208, known as "ELEMENT OF," is a crucial symbol in mathematical notation and scientific writing. Its primary role is to denote the element of a set or the element that an operation acts upon. Typically used in digital text, it enables readers to easily identify the subject of a specific operation or equation. In computer science and programming languages, U+2208 is employed to signify the selection or extraction of elements from data structures like lists, arrays, and matrices. Furthermore, its usage in linguistics and cultural contexts is limited; however, it is occasionally seen in mathematical texts across various scientific disciplines such as physics, chemistry, and engineering. By accurately representing elements within sets or operations, U+2208 plays a vital role in the precise communication of complex concepts in both academic and professional settings.
