Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+218D. 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+218D to binary:
00100001 10001101. 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 10000110 10001101

Description
U+218D is a unique character in the Unicode Standard, representing the Black Small Square (⡍) symbol. This typographical element is primarily used for digital text formatting to create spacing, alignment, or design elements within a document or graphic. In certain cultural contexts, it may be employed as an artistic decorative element or within specific linguistic systems that utilize non-Latin scripts. Although not widely recognized in mainstream communication, the Black Small Square symbol serves a crucial role in niche applications where precise layout control is required.
