Step 1: Determine the UTF-8 encoding bit layout
The character ℿ has the Unicode code point U+213F. 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+213F to binary:
00100001 00111111
. 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 10111111

Description
The Unicode character U+213F, known as the DOUBLE-STRUCK CAPITAL PI, plays a vital role in various digital text applications. As a typographical symbol, it is predominantly used in mathematical expressions, scientific notations, and technical documentation to signify capital pi. This character is double-struck, meaning that it appears as if enclosed by a pair of parallel vertical lines, visually emphasizing its presence. The use of this character in digital text often helps to distinguish constants or variables from ordinary text, enhancing readability and reducing ambiguity in these contexts. The DOUBLE-STRUCK CAPITAL PI is not tied to any specific cultural, linguistic, or regional context, but it contributes significantly to the clarity and precision of communication in fields that rely on mathematical and technical notation.
