Step 1: Determine the UTF-8 encoding bit layout
The character ∀ has the Unicode code point U+2200. 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+2200 to binary:
00100010 00000000. 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 10001000 10000000

Description
The Unicode character U+2200, also known as "For All," is a mathematical symbol used to denote universality or all possible values of a variable within a specific set. In digital text, it commonly appears in mathematical formulas and expressions where the concept of universality or totality needs to be communicated. This character is particularly useful in computer programming, where it helps to define the scope of variables and functions. U+2200 holds significance in both technical and linguistic contexts, as it bridges the gap between mathematics and programming languages. It ensures accurate representation of concepts that involve a wide range of values or elements within a specific set, thereby contributing to the clarity and precision of digital text.
