Step 1: Determine the UTF-8 encoding bit layout
The character ↲ has the Unicode code point U+21B2. 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+21B2 to binary:
00100001 10110010. 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 10000110 10110010

Description
The Unicode character U+21B2, known as the "DOWNWARDS ARROW WITH TIP LEFTWARDS," is a symbol often used in digital text for mathematical expressions, particularly in physics and engineering contexts. Its primary role is to indicate a vector or direction that points downward and slightly leftwards. In certain technical fields such as physics or computer graphics, this arrow may be utilized in equations or diagrams to depict vectors or arrows indicating movement or direction. Its usage stems from the broader category of mathematical symbols in Unicode, which provides a wide range of characters for use in mathematical notation and expressions. U+21B2 is part of the "Mathematical Symbols" block of Unicode characters that cater to the representation of various mathematical notations and symbols required for accurate communication in scientific fields. The character itself holds no cultural or linguistic significance, but serves as a technical tool for precise representation of vectors, directions, and arrows in digital text.
