Step 1: Determine the UTF-8 encoding bit layout
The character ⇉ has the Unicode code point U+21C9. 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+21C9 to binary:
00100001 11001001. 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 10001001

Description
The Unicode character U+21C9 is the "RIGHTWARDS PAIRED ARROWS" symbol, which is commonly used in digital text for denoting a rightward directional change in flowcharts or pseudocode. This particular character has a unique role in representing two arrows facing each other and pointing to the right. It plays a significant role in programming languages and computer software that require graphical representation of algorithms, logic flow, data structures, or any instance where bidirectional movement is represented visually. The RIGHTWARDS PAIRED ARROWS symbol, although not culturally specific, can be found across various linguistic contexts due to the global acceptance and use of Unicode. As part of the Unicode Standard, it ensures uniformity in text encoding, paving way for accurate and consistent communication across digital platforms. It's critical to note that U+21C9 is not just a decorative character; rather, it serves as an essential tool in various technical fields such as computer science, data visualization, and software design.
