Description

The Unicode character U+303D, known as the Part Alternation Mark (パート・アルテネーション・マーク), is a typographical symbol primarily used in digital text for its role in representing alternating parts of specific characters. This character is often utilized in Japanese and Chinese typography systems to denote alternative pronunciations or readings of a single character. It has significant cultural, linguistic, and technical importance due to its application in the accurate representation of traditional texts and the preservation of historic language nuances in the digital age. The Part Alternation Mark plays a critical role in maintaining the integrity of these languages as it ensures that the intended meanings are accurately conveyed in written form, despite potential alterations or adaptations in pronunciation over time. Its usage helps bridge the gap between traditional and modern textual forms while maintaining the rich linguistic heritage present within these ancient scripts.

How to type the symbol on Windows

Hold Alt and type 12349 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+303D. 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+303D to binary: 00110000 00111101. 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 10111101
