Description

U+2438 is a character in the Unicode standard that represents the symbol ℘. This typographical glyph is known as the "Middle Point" and is primarily used in mathematical notation, particularly within the field of engineering and computer science. It signifies a value or quantity in the middle between two other values. While it may not have significant cultural or linguistic context, its use in various technical disciplines emphasizes its importance in conveying precise information. Its role in digital text is to facilitate clear communication and understanding within these specialized domains, enabling professionals to express complex ideas with clarity and precision.

How to type the symbol on Windows

Hold Alt and type 9272 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+2438. 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+2438 to binary: 00100100 00111000. 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 10010000 10111000
