Step 1: Determine the UTF-8 encoding bit layout
The character ⭑ has the Unicode code point U+2B51. 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+2B51 to binary:
00101011 01010001. 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 10101101 10010001

Description
The Unicode character U+2B51 is known as the Black Small Star. This typographical symbol holds a distinct place within the realm of digital text, primarily due to its versatile applications across various fields. Typically used in programming and computer science, this character serves as an indicator for operations like multiplication (*) in certain programming languages when combined with U+22C5 (Multiplication Sign). Furthermore, it is often employed in mathematical expressions or equations where a star symbol is desired instead of the more common asterisk. Though not widely used in everyday text, the Black Small Star has a unique role within specific technical and linguistic contexts that value its distinct visual appeal and precise functionality. Its use as an alternative to the conventional asterisk underscores the rich diversity that Unicode offers for digital text expression.
