Step 1: Determine the UTF-8 encoding bit layout
The character ⇁ has the Unicode code point U+21C1. 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+21C1 to binary:
00100001 11000001. 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 10000111 10000001

Description
The Unicode character U+21C1, known as the Rightwards Harpoon with Barb Downwards, is a typographic symbol primarily used in digital text for mathematical and scientific notation. It represents a directional vector or an arrow pointing to the right and has a downward-facing barb at its tip. This specialized character allows authors and researchers to precisely describe vectors and flows in various contexts such as physics, engineering, and fluid dynamics. Although not widely used in everyday typography, it holds significant importance within these specific fields for accurate communication of technical concepts.
