Step 1: Determine the UTF-8 encoding bit layout
The character ℾ has the Unicode code point U+213E. 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+213E to binary:
00100001 00111110. 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 10111110

Description
The Unicode character U+213E, known as the DOUBLE-STRUCK CAPITAL GAMMA (℘), is a symbol used in digital text to represent a specific mathematical or technical concept. It plays a significant role in various fields such as engineering, computer science, and physics. The double-struck capital gamma character is particularly useful for denoting the ideal gas constant (R) when it is necessary to differentiate between the constant itself and its natural logarithm (ln(R)). This ensures clarity and precision in scientific and technical documentation. Despite not being widely used or recognized in everyday language, U+213E holds importance in specialized domains for its clear distinction between similar symbols and concepts, enhancing communication and understanding within expert communities.
