Step 1: Determine the UTF-8 encoding bit layout
The character ℑ has the Unicode code point U+2111. 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+2111 to binary:
00100001 00010001. 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 10010001

Description
The Unicode character U+2111, known as the Black-Letter Capital I (⩲), serves a unique function within the realm of typography and digital text. This distinct letter is not commonly used in everyday language but holds significance in certain contexts. It is often employed in the creation of customized or unique font designs where it can add an antique or historical feel to written content. The Black-Letter Capital I finds its origins in the handwritten scripts of the Middle Ages, where scribes would use a specific style known as 'textura' or 'Gothic textura.' In this script, the letter 'I' was often depicted with an elongated vertical stroke and an angular bottom terminal, giving it a distinct appearance from its modern counterpart. As a result, U+2111 offers a way to incorporate elements of historical calligraphy into digital communication, enhancing the visual interest and appeal of text for those who appreciate such typographic nuances.
