Description

The Unicode character U+22EC, known as "Not Normal Subgroup of or Equal To", is a specialized symbol used primarily within the realm of digital text for mathematical expressions and computer programming languages. This character serves a critical role in establishing certain relationships between sets, particularly when comparing subgroups to determine if they are normal or abnormal in context. Its significance is largely rooted in its ability to convey complex mathematical concepts concisely, facilitating clearer communication and reducing the risk of misinterpretation among professionals in fields such as mathematics, computer science, and engineering. Despite its specific use case, U+22EC remains an important symbol within digital text, highlighting the power of Unicode's extensive character set to facilitate precise expression across a wide range of languages and disciplines.

How to type the symbol on Windows

Hold Alt and type 8940 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+22EC. 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+22EC to binary: 00100010 11101100. 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:
