Description

U+25DA, also known as the Upper Half Inverse White Circle, is a Unicode character primarily used in the realm of typography and digital text formatting. This enigmatic symbol is part of the Box Drawing Characters set, specifically the subset called "Inverse Characters." These characters are designed to create contrasting borders and content blocks within digital text. The Upper Half Inverse White Circle, as its name suggests, is typically used in combination with other inverse characters to create inverted rectangles or squares for highlighting, separating, or emphasizing sections of text. Its application can be observed in coding environments, documentation, and certain design projects where the use of typography elements aids in structuring content visually. Despite its relatively obscure nature, the Upper Half Inverse White Circle plays a crucial role in the realm of digital text formatting, providing designers and developers with valuable tools to enhance readability and organization in their work.

How to type the symbol on Windows

Hold Alt and type 9690 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+25DA. 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+25DA to binary: 00100101 11011010. 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 10011010
