Step 1: Determine the UTF-8 encoding bit layout
The character ∟ has the Unicode code point U+221F. 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+221F to binary:
00100010 00011111. 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 10001000 10011111

Description
The Unicode character U+221F is known as the "Right Angle" symbol. It is commonly employed in mathematical equations and digital text to represent a right angle, which measures 90 degrees. This symbol is particularly useful in geometry, trigonometry, and other mathematical disciplines where angles and their relationships are critical concepts. The Right Angle character can also be utilized in diagrams and illustrations to clearly depict a right-angled corner or bend. While it may seem like a simple symbol, the Right Angle has profound significance in various fields such as computer science, engineering, and physics, where precise representation of angles is crucial for accurate calculations and problem-solving. Overall, U+221F serves as an essential tool in conveying complex ideas and relationships with clarity and precision.
