Description

The Unicode character U+234C represents the APL Functional Symbol Quad Down Caret (⌽). This mathematical symbol is primarily used in digital text for its role in representing the reverse of an APL function or arrow. It is part of the APL (Association for Computing Machinery) functional notation system, which was developed by American mathematician and computer scientist Charles H. Wadsworth as an extension to standard arithmetic notation. The Quad Down Caret symbol (⌽) is used in mathematical expressions to denote that the function or arrow is applied in reverse order. Although its use may be relatively rare outside of specialized contexts like APL programming and notation systems, it remains a vital tool for those working within these specific domains.

How to type the symbol on Windows

Hold Alt and type 9036 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+234C. 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+234C to binary: 00100011 01001100. 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 10001101 10001100
