Step 1: Determine the UTF-8 encoding bit layout
The character ₊ has the Unicode code point U+208A. 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+208A to binary:
00100000 10001010. 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 10000010 10001010

Description
The Unicode character U+208A, known as the Subscript Plus Sign (₊), plays a crucial role in mathematical expressions and scientific notations within digital text. Its primary function is to represent an operation of addition that should be applied at a subscript level. This character helps users convey complex mathematical equations with greater precision, enabling clearer communication across various disciplines such as mathematics, physics, and engineering. Despite its limited usage in everyday writing, the Subscript Plus Sign is an indispensable tool for professionals and scholars who require accuracy and specificity when dealing with subscripted variables or terms.
