Step 1: Determine the UTF-8 encoding bit layout
The character ⇏ has the Unicode code point U+21CF. 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+21CF to binary:
00100001 11001111. 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 10001111

Description
The Unicode character U+21CF, known as the "RIGHTWARDS DOUBLE ARROW WITH STROKE," serves a specific role in digital text as an arrow symbol that indicates direction. In its typical usage, it is used to represent a rightward motion with a distinct stroke or line through the center of the arrowhead, distinguishing it from other directional symbols. This character may be utilized in various contexts such as mathematics, logic, and diagramming, where precise directions are essential for clarity and understanding. While there isn't any notable cultural, linguistic, or technical context associated with this specific character, its presence in Unicode demonstrates the breadth and versatility of the character encoding system, enabling accurate communication and representation across different languages and platforms.
