Description

The Unicode character U+2557 represents the "BOX DRAWINGS DOUBLE DOWN AND LEFT" symbol. This particular character is used in digital text to depict a box with a double vertical line on the left side and a single horizontal line at the top, resembling a partially constructed right-angled isosceles triangle. The Box Drawings series of characters are frequently employed in programming and markup languages for creating borders, dividers, or visual elements within user interface designs, code comments, or as a part of text-based artwork. While not tied to any specific cultural or linguistic context, the use of these box characters is widespread across different programming and markup languages such as HTML, CSS, and Unicode itself. By utilizing these symbols, developers and designers can create visually appealing layouts and structures while maintaining accuracy and functionality in their digital creations.

How to type the symbol on Windows

Hold Alt and type 9559 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+2557. 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+2557 to binary: 00100101 01010111. 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 10010101 10010111
