Description

The Unicode character U+2BD9 is known as Astraea, an astronomical symbol representing the star or constellation Cassiopeia. In digital text, this symbol is often used in astrology, astronomy, and other scientific fields to denote this particular celestial object. Astraea holds significance in cultural and linguistic contexts due to its association with Greek mythology, where it is the name of a nymph who personified justice. The character U+2BD9 has no widely-used technical applications outside of its specific symbolic role but remains an essential tool for scholars and researchers working within fields related to astronomy and celestial bodies.

How to type the symbol on Windows

Hold Alt and type 11225 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+2BD9. 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+2BD9 to binary: 00101011 11011001. 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 10011001
