Step 1: Determine the UTF-8 encoding bit layout
The character ∠ has the Unicode code point U+2220. 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+2220 to binary:
00100010 00100000. 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 10100000

Description
The Unicode character U+2220 represents the mathematical symbol for angle (∡), also known as the degree sign or versor. This symbol is commonly used in digital text to denote an angle or a degree measure in various fields such as mathematics, physics, engineering, and computer graphics. Its usage is prevalent in equations, formulas, and technical documentation that require precise representation of angles or degrees. The U+2220 character is part of the Mathematical Operators block in Unicode, which consists of a wide range of symbols used to represent mathematical notations, operations, and relations. There isn't any specific cultural, linguistic, or technical context associated with this character, as its primary purpose is to provide accurate representation of angle measurements across different languages and platforms that use the Unicode standard for text encoding.
