Description

The Unicode character U+231F is known as the "Bottom Right Corner" (⊿). This typographical symbol holds a significant role in digital text, especially in mathematical equations and diagrams. In such contexts, it serves to represent the bottom right corner of a square or rectangle, often used in geometric constructs and spatial analysis. Its usage is prominent in computer science, engineering, and mathematics, where precise visualization of geometric shapes is crucial for understanding complex concepts. Despite its specialized use, U+231F's significance transcends linguistic boundaries due to the universality of Unicode encoding.

How to type the symbol on Windows

Hold Alt and type 8991 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+231F. 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+231F to binary: 00100011 00011111. 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 10001100 10011111
