Description

The character U+2373, also known as the APL Functional Symbol Iota (⍠), plays a significant role in the digital text domain, specifically within the realm of typography and computer science. This unique symbol is predominantly used in the field of Applied Mathematics, particularly in the programming language APL (A Programming Language). It represents the functional Iota operator in APL, which when applied to an input function or expression, returns the first argument of the function or expression. The APL Functional Symbol Iota is an essential part of APL's concise notation system and is often utilized for its compact representation of complex mathematical expressions. While U+2373 may not be widely recognized outside of specialized communities, it holds considerable cultural, linguistic, and technical significance within the domain of APL programming. As APL is known for its powerful, elegant syntax and efficient computation capabilities, the APL Functional Symbol Iota reflects the language's dedication to concise and expressive communication in mathematical computations. In summary, the character U+2373, or the APL Functional Symbol Iota, holds a vital role within the digital text realm, particularly within the programming language APL. It represents the functional Iota operator, which is crucial for concise expression of complex mathematical concepts and efficient computation. While not universally recognized, its significance lies in its application to APL's unique notation system and the programming language's rich cultural, linguistic, and technical context.

How to type the symbol on Windows

Hold Alt and type 9075 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+2373. 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+2373 to binary: 00100011 01110011. 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 10110011
