Step 1: Determine the UTF-8 encoding bit layout
The character ℸ has the Unicode code point U+2138. 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+2138 to binary:
00100001 00111000. 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 10000100 10111000

Description
The Unicode character U+2138, commonly known as the Dalet Symbol, serves a crucial role in digital typography. It is derived from the Hebrew letter 'Dalet' (ד), which represents both the consonantal sound /d/ and the Arabic numeral four in the ancient Semitic abjads. This character has found significant usage in mathematics, computer science, and programming, primarily as a symbol for the digital binary state or data structure. In these contexts, it often denotes the bitwise negation of a binary value, or signifies a "do-nothing" action or operation. The Dalet Symbol's versatility and distinct visual appeal make it an essential addition to the typographer's toolkit, contributing to clearer communication and more engaging digital content across various applications and industries.
