Description

The character U+3005, known as the IDEOGRAPHIC ITERATION MARK, plays a significant role in digital text, particularly within the context of Japanese typography. This symbol serves to indicate that a preceding ideographic character should be considered in a different form or reading than its standard representation. It is primarily used in dictionaries and other reference materials to show alternative readings or pronunciations for a particular Kanji character. In essence, it helps disambiguate homophones or characters with multiple meanings by clarifying the intended usage within a specific context. Thus, the IDEOGRAPHIC ITERATION MARK is an essential tool in written communication and a critical component of Japanese typography.

How to type the symbol on Windows

Hold Alt and type 12293 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+3005. 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+3005 to binary: 00110000 00000101. 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 10000101
