Description

The Unicode character U+23B5, also known as BOTTOM SQUARE BRACKET, is a specialized typographical symbol primarily used in digital text for various purposes, such as coding, programming, and mathematical expressions. It serves to denote the opening square bracket at the bottom of an element or object, contrasting with the top-oriented UPPER SQUARE BRACKET (U+23B4). Despite its limited usage in common language, this character plays a vital role in certain technical fields like computer programming and mathematics, where it assists in defining structures, arrays, and sets. In programming languages such as C, C++, Java, and Pascal, U+23B5 is often employed within square brackets to indicate array indexing or accessing elements of a data structure. In mathematical notations, it can be utilized to represent an element at the bottom of a geometric object. The usage of this character requires an understanding of its contextual role in coding and mathematical expressions.

How to type the symbol on Windows

Hold Alt and type 9141 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+23B5. 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+23B5 to binary: 00100011 10110101. 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:
