Description

The Unicode character U+25F7, also known as the White Circle with Upper Right Quadrant, is a versatile typographic symbol commonly employed in digital text to represent a variety of concepts across different fields. In mathematics, it serves as an indicator for open or closed intervals within real numbers, denoting that values on the left side are less than or equal to, and values on the right side are greater than or equal to a specific number. In computer programming, U+25F7 is frequently used to signify an empty cell in tables or grids, providing visual cues for users when data is not present. It also plays a role in graphic design as a simple, unobtrusive graphic element that can be easily inserted and manipulated within digital layouts. Although it may not carry significant cultural or linguistic significance on its own, U+25F7's flexibility and adaptability make it an essential tool for clear communication across various disciplines in the digital world.

How to type the symbol on Windows

Hold Alt and type 9719 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+25F7. 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+25F7 to binary: 00100101 11110111. 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 10110111
