Description

The character U+3121 is known as the BOPOMOFO LETTER OU. It plays a significant role in digital texts, particularly those involving the Bopomofo script, which is used to transcribe Mandarin Chinese into the Latin alphabet. Bopomofo is an abugida system that represents both consonants and vowels. This character represents a unique sound combination of 'o' and 'u' in Mandarin Chinese. The Bopomofo script is widely used for teaching purposes, especially for non-native speakers learning Mandarin Chinese. Despite its specific usage, U+3121 holds cultural significance as it reflects the diversity of written languages and systems employed around the world.

How to type the symbol on Windows

Hold Alt and type 12577 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+3121. 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.

    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+3121 to binary: 00110001 00100001. 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:
    11100011 10000100 10100001
