Description

The Unicode character U+25D0, known as the "Circle with Left Half Black", is a typographical symbol that serves a specific purpose in digital text. It is often used to create visual separators or dividers within text content, helping to delineate sections or blocks of information. Its distinctive appearance comprises a circle split horizontally, with the left half appearing black, while the right half remains transparent or white. This character can be employed in various contexts, such as creating diagrams, flowcharts, or other visual aids where precise division is necessary. It's worth noting that U+25D0 is part of a larger family of Unicode characters designed for similar purposes, including the "Circle with Right Half Black" (U+25D1) and the "Circle with Top Half Black" (U+25D2), each serving their own distinct roles in digital typography.

How to type the symbol on Windows

Hold Alt and type 9680 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+25D0. 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+25D0 to binary: 00100101 11010000. 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:
