Step 1: Determine the UTF-8 encoding bit layout
The character ⬆ has the Unicode code point U+2B06. 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+2B06 to binary:
00101011 00000110. 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 10101100 10000110

Description
The Unicode character U+2B06 is known as the "UPWARDS BLACK ARROW". In digital typography, this symbol is often used to indicate movement in a positive direction or an increase in a value. Its most common application can be found within mathematical equations and scientific notations, where it represents a derivative, a differential, or an incremental change. For instance, in calculus, the arrow signifies that the function is differentiable at the given point. Additionally, it can also be utilized in computer programming to denote upcasting or the process of converting a less specific type into a more specific one. Despite its technical connotations, this character remains culturally and linguistically neutral due to its universal recognition across all languages that utilize the Unicode system.
