Step 1: Determine the UTF-8 encoding bit layout
The character ⇴ has the Unicode code point U+21F4. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+21F4 to binary:
00100001 11110100
. 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:

Description
The Unicode character U+21F4, known as RIGHT ARROW WITH SMALL CIRCLE, is a typographic symbol used in digital text to denote an arrow pointing to the right, with a small circle surrounding the tip of the arrow. This character is typically employed in mathematical notation and computer programming for representing certain arrows or directions in algorithms or diagrams. While it doesn't have any specific cultural, linguistic, or technical context beyond its role as a specialized symbol in these fields, it serves an important purpose in enhancing clarity and readability of the material it is used within. The Unicode character U+21F4 contributes to the precision and conciseness of mathematical equations and programming code, making complex concepts easier to understand for those who are familiar with its usage.
