Description

The Unicode character U+2344, known as the APL Functional Symbol Quad Greater-Than, is primarily used to represent a greater-than sign in a quadrilateral shape within digital text. This character is often employed in the field of computer programming and mathematics, particularly in the domain of the esoteric programming language, APL (A Programming Language), developed by Kenneth E. Iverson. The symbol serves as an important component for expressing mathematical relationships and hierarchical structures, and its unique, quadrilateral form sets it apart from the standard greater-than sign (>). Although this character may not be commonly found in everyday digital communication, it holds significance within niche communities of programmers, mathematicians, and APL enthusiasts.

How to type the symbol on Windows

Hold Alt and type 9028 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+2344. 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+2344 to binary: 00100011 01000100. 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 10000100
