Description

The Unicode character U+2BE9, known as the RIGHT HALF BLACK STAR, is a typographical symbol that plays a significant role in digital text representation. This character is primarily used for its visual appearance, which consists of a right-facing star with a black fill. It's often employed to add an aesthetic touch to various forms of digital communication, including websites, emails, and messaging platforms. The RIGHT HALF BLACK STAR does not have any specific cultural, linguistic, or technical context associated with it, making its usage flexible across different languages and regions. Its use is generally limited to design purposes where a unique star symbol is required. Since it's an obscure character, it may not be supported by all digital platforms, necessitating the use of fallback symbols or alternative characters when necessary.

How to type the symbol on Windows

Hold Alt and type 11241 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+2BE9. 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+2BE9 to binary: 00101011 11101001. 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 10101111 10101001
