Description

The Unicode character U+257B, also known as "BOX DRAWINGS HEAVY DOWN," serves a critical role in digital text by representing a heavy downward-pointing arrow or triangle within box drawers. It is often used in programming languages and markup languages to define the direction of data flow, directional movement in algorithms, or to illustrate hierarchical structures visually. This character is predominantly utilized in diagrams, flowcharts, pseudo-code, programming manuals, documentation, and other technical documents for its visual clarity and precision. In various programming contexts, it can be used as an escape sequence like '\u257B' or '◃'. Despite not having any notable cultural or linguistic significance, its usage in the technical field is vital to maintain accuracy, coherence, and comprehensibility of textual information.

How to type the symbol on Windows

Hold Alt and type 9595 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+257B. 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+257B to binary: 00100101 01111011. 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 10111011
