Step 1: Determine the UTF-8 encoding bit layout
The character ⇙ has the Unicode code point U+21D9. 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+21D9 to binary:
00100001 11011001. 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 10011001

Description
The Unicode character U+21D9, known as the South West Double Arrow, is a lesser-known symbol that holds specific significance in certain fields. Typically employed within digital text to represent directions or navigation, this arrow points southwestward and can be used alongside other directional arrows like North East Double Arrow (U+21DA) and others. Although not as commonly utilized as other directional symbols, it remains a valuable tool in contexts where precise geographical information is required.
