Step 1: Determine the UTF-8 encoding bit layout
The character ℜ has the Unicode code point U+211C. 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+211C to binary:
00100001 00011100. 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 10011100

Description
The Unicode character U+211C, also known as the Black-Letter Capital R, is a typographic symbol used primarily in digital text for its distinct appearance and aesthetic value. This unique character has its roots in the historical tradition of blackletter typefaces, which were widely used in European print materials from the 14th to 17th centuries. The Black-Letter Capital R represents an early form of the letter "R" with a more decorative and calligraphic design compared to the modern uppercase R. In digital text, it is often used for its artistic or historical significance, such as in designing logos, headings, or other typographic projects that require a sense of antiquity or formality. Despite not having a direct linguistic role, the Black-Letter Capital R contributes to the richness and diversity of visual language in digital text.
