Description

The Unicode character U+2353, also known as the APL Functional Symbol Quad Up Caret, is a specialized mathematical symbol primarily used in digital text for its role in the field of applied mathematics and computer science. It was specifically designed for use within the notation system of the programming language APL (A Programming Language), which heavily relies on symbols rather than standard alphanumeric characters for its syntax. The APL Functional Symbol Quad Up Caret is a critical element in this symbolic notation, as it serves to denote a specific mathematical operation or function within the APL system. While not widely known outside of specialized contexts, this character plays an important role in advanced computational and analytical workflows that utilize APL's unique syntax.

How to type the symbol on Windows

Hold Alt and type 9043 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+2353. 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+2353 to binary: 00100011 01010011. 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 10010011
