Description

The Unicode character U+237D, known as the Shouldered Open Box, is a typographical symbol commonly used in digital text to represent an open box with two angled lines sloping upwards from its base. This character finds its application primarily in technical and mathematical contexts, serving to enclose or surround quantities, equations, or other expressions where visual emphasis or demarcation is required. While it doesn't have a direct cultural, linguistic, or technical significance, the Shouldered Open Box is often used in conjunction with other mathematical symbols and notations, including brackets, parentheses, and curly braces, to enhance readability and comprehension of complex equations or data sets. In terms of typography, its unique design differentiates it from other box-like characters like the Open Box (U+237E) and the Horizontal Ellipsis (U+2026), ensuring clear distinction and enhancing the overall visual appeal of digital text where it is used.

How to type the symbol on Windows

Hold Alt and type 9085 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+237D. 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+237D to binary: 00100011 01111101. 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 10111101
