Description

The Unicode character U+25E5, known as the Black Upper Right Triangle, is a geometric symbol that primarily serves a role in digital text for representing an open angle or a directional indicator. It is often used in diagrams, flowcharts, and mathematical notations to denote an upward-opening right triangle. The character's shape consists of a thick, black triangle pointing to the upper right corner. In technical contexts, U+25E5 is utilized in ASCII art, where it helps create visual effects or illustrate concepts without relying on color or complex graphics. It is also employed in programming and markup languages for structuring text layout and formatting. Although this symbol doesn't have any specific cultural or linguistic significance, it does contribute to clearer communication and improved readability in various digital applications.

How to type the symbol on Windows

Hold Alt and type 9701 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+25E5. 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+25E5 to binary: 00100101 11100101. 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 10010111 10100101
