Step 1: Determine the UTF-8 encoding bit layout
The character ⊰ has the Unicode code point U+22B0. 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+22B0 to binary:
00100010 10110000. 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 10001010 10110000

Description
The Unicode character U+22B0, also known as the "Precedes Under" relation symbol (⊏), plays a crucial role in mathematical notation and formal logic systems within digital text. This character is part of the Mathematical Operators block in the Unicode Standard, which encompasses various symbols used to express mathematical operations and relationships. The Precedes Under symbol specifically signifies that one mathematical expression precedes another in a certain context, often denoting the lower bound of an inequality or interval. Its usage is particularly prominent in algebraic expressions, set theory, and calculus, where it helps to define the scope and bounds of various relationships, limiting cases, and inequalities. In digital typography, U+22B0 ensures clear communication of these concepts by providing a distinct visual cue for readers familiar with mathematical notation.
