Description

The Unicode character U+3309, known as the SQUARE ONSU, is a typographical symbol that holds importance in digital text representation. It is primarily used to represent the concept of "On's" in certain East Asian languages and scripts. The SQUARE ONSU symbol has been designed specifically for this purpose, making it easier for readers to distinguish between different characters or words within these languages. In linguistic and cultural contexts, the SQUARE ONSU character is critical in accurately conveying meaning, as it assists in distinguishing between words that could otherwise be misinterpreted due to visual similarities. For instance, in Japanese and Chinese scripts, where many characters share common strokes or shapes, the SQUARE ONSU serves as a vital differentiator for on-reading and kana readings. From a technical standpoint, the SQUARE ONSU character is part of the Unicode Standard, which ensures consistent encoding and display across various devices and software. The Unicode Consortium, responsible for creating and maintaining this standard, has assigned U+3309 to facilitate proper representation and interpretation of the symbol in digital communication and data processing systems.

How to type the symbol on Windows

Hold Alt and type 13065 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+3309. 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+3309 to binary: 00110011 00001001. 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 10001100 10001001
