Step 1: Determine the UTF-8 encoding bit layout
The character ℱ has the Unicode code point U+2131. 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+2131 to binary:
00100001 00110001. 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 10110001

Description
The Unicode character U+2131 represents the "Script Capital F" in digital text. This typographical symbol is primarily used to denote the beginning of a new section or heading within a document or publication. In typography, it serves as an alternative to the traditional uppercase "F" for creating distinct visual hierarchy and formatting in written content. The Script Capital F character holds no specific cultural or linguistic significance, as its usage is primarily based on typographical conventions rather than language or region-specific rules. Its primary function lies within the realm of digital text processing and design, where it aids in organizing information and enhancing readability for users. In terms of technical context, the Script Capital F character can be encountered in various software applications that support Unicode, such as word processors, typesetting tools, and web browsers. It is commonly used in scenarios requiring a unique heading style or when designers seek to avoid potential confusion between standard uppercase "F" and other similar-looking characters within their documents.
