Description

U+227C, known as the "Precedes or Equal To" symbol (≆), is a mathematical symbol in Unicode that serves to indicate a relationship between two elements. In digital text, it is typically used in set theory and order relations to denote that one element precedes another in a given sequence or that they are equal. This symbol plays a crucial role in various fields such as computer science, mathematics, and logic. The Precedes or Equal To sign can be found within the Miscellaneous Technical Symbols Unicode block, which includes symbols predominantly used for mathematical, technical, and scientific purposes.

How to type the symbol on Windows

Hold Alt and type 8828 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+227C. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    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 the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+227C to binary: 00100010 01111100. Those are the payload bits.

  3. 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 10001001 10111100
