Step 1: Determine the UTF-8 encoding bit layout
The character ℂ has the Unicode code point U+2102. 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+2102 to binary:
00100001 00000010. 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 10000010

Description
The Unicode character U+2102, known as the DOUBLE-STRUCK CAPITAL C, serves a distinct purpose in the realm of digital text. This unique typographical element is designed to distinguish itself through its dual-struck appearance, where it appears bolded twice for added emphasis or clarity. The double-struck format is typically used within mathematical and scientific contexts, where it can differentiate between similar symbols and aid in readability. This character is also prevalent in certain programming languages, as well as in various technical documents and equations. Although it may not hold significant cultural or linguistic value, the DOUBLE-STRUCK CAPITAL C remains an important typographical tool for specific use cases in digital text.
