Step 1: Determine the UTF-8 encoding bit layout
The character ⍏ has the Unicode code point U+234F. 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+234F to binary:
00100011 01001111. 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 10001101 10001111

Description
The Unicode character U+234F, known as the APL Functional Symbol Upwards Vane, holds a significant position in digital typography and mathematical notation. It is primarily used to denote an upward-facing arrow, often employed within APL (A Programming Language) syntax for indicating direction or flow of computation in algorithms and complex equations. The character's use extends beyond programming into mathematics, particularly in diagrammatic representation of functions, where it symbolizes a derivative or rate of change. Despite being less common compared to more widely-used arrow symbols like the right-angle arrow (U+2192) or left-angle arrow (U+2190), U+234F holds a crucial role in niche fields such as computer science, mathematics, and technical documentation. Its usage enhances readability and accuracy of textual content in these specialized domains by providing a clear visual indication of direction and flow.
