Step 1: Determine the UTF-8 encoding bit layout
The character ₛ has the Unicode code point U+209B. 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+209B to binary:
00100000 10011011. 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 10011011

Description
The Unicode character U+209B is known as the Latin Subscript Small Letter S. It plays a significant role in digital typography by representing a lowercase 's' when it appears in a subscript position within text. This character is particularly useful for displaying mathematical or chemical formulas, where subscripts are commonly used to denote different elements, isotopes, or variables. Despite being less common in everyday language use, the Latin Subscript Small Letter S contributes to clarity and accuracy when employed in specialized contexts such as scientific documentation, chemistry, or mathematics. Its presence within Unicode ensures that users across various languages and platforms can consistently create and interpret documents with subscript notation, promoting consistency and understanding in these technical disciplines.
