Step 1: Determine the UTF-8 encoding bit layout
The character ₋ has the Unicode code point U+208B. 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+208B to binary:
00100000 10001011. 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 10001011

Description
The Unicode character U+208B, known as SUBSCRIPT MINUS (‑), is a typographical symbol used in digital text for expressing minus values or subtractive operations in a mathematical context. It is typically found in scientific documents, equations, and technical writing where precise representation of mathematical concepts is required. While U+208B might not be commonly encountered in everyday text, it plays an essential role in various fields, such as physics, engineering, and chemistry, where accurate expression of subtractive operations or values is crucial for maintaining the integrity of the information being conveyed.
