Description

U+2E57, the Left Square Bracket with Double Stroke, is a unique typographic character primarily employed in digital text to create visually distinct square brackets for various purposes, such as marking off sections of text or indicating a range of values. This Unicode character distinguishes itself from its counterparts through its double-stroke design, which consists of two parallel horizontal lines intersecting the vertical line that forms the standard square bracket. Although not part of any widely used language or script, the Left Square Bracket with Double Stroke may be utilized in specialized fields like programming, mathematics, or typography for a distinctive visual effect or to emphasize specific sections of text. While it might not have a prominent cultural or linguistic context, its use can help enhance readability and clarity within specific digital text scenarios.

How to type the symbol on Windows

Hold Alt and type 11863 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+2E57. 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+2E57 to binary: 00101110 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 10111001 10010111
