Description

The Unicode character U+234B represents the "APL Functional Symbol Delta Stile" in digital text. This symbol is typically used in programming, specifically in APL (A Programming Language) which is a specialized language designed for mathematical computations and data manipulation. Developed by Kenneth E. Iverson in 1962, APL is renowned for its concise syntax and ability to perform complex calculations using a subset of the English alphabet. The Delta Stile symbol (∆) serves as a fundamental operator in APL, indicating a change or difference between two values. In APL, the Delta Stile is used in various operations such as subtraction, finite differences, and discrete calculus. Despite its niche application, the APL Functional Symbol Delta Stile holds significance in programming and computational linguistics due to its role in a highly efficient and expressive language.

How to type the symbol on Windows

Hold Alt and type 9035 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+234B. 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+234B to binary: 00100011 01001011. 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 10001011
