Description

The Unicode character U+302C, also known as the IDEOGRAPHIC DEPARTING TONE MARK, is a crucial element in digital text, particularly in languages like Chinese, Japanese, Korean (CJK), and other East Asian scripts. Its role is to indicate changes in tones, which are essential for conveying meaning in these languages where tone can significantly alter the meaning of words. The IDEOGRAPHIC DEPARTING TONE MARK specifically marks the beginning of a new syllable block, differentiating it from a preceding one that may have its own tonal indicators. This allows for more nuanced communication and helps avoid misinterpretations in text, which is especially critical given the vast number of users who rely on digital platforms for written communication.

How to type the symbol on Windows

Hold Alt and type 12332 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+302C. 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+302C to binary: 00110000 00101100. 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 10000000 10101100
