Step 1: Determine the UTF-8 encoding bit layout
The character ℙ has the Unicode code point U+2119. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+2119 to binary:
00100001 00011001
. 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 10011001

Description
The Unicode character U+2119, known as the DOUBLE-STRUCK CAPITAL P, is a typographical representation that plays a significant role in digital text. This specific character is often employed to convey a sense of emphasis or importance in written content, much like bold or italicized text. Its double-struck design, where the letters appear to be enclosed within a border, lends it a distinctive visual appeal that makes it an attractive option for headings or title case usage. In technical contexts, the DOUBLE-STRUCK CAPITAL P may be used in mathematical notation, equations, and computer science applications where it serves to differentiate certain symbols or variables from others. This character's unique design helps prevent any possible confusion that might arise when reading complex formulas or algorithms, enhancing readability and overall comprehension. Despite being less common than other Unicode characters, the DOUBLE-STRUCK CAPITAL P still holds a valuable position in digital typography. Its versatility and ability to convey emphasis make it an essential tool for designers and content creators alike, contributing to the richness and variety of textual expression available through modern digital technology.
