Description

The Unicode character U+31D9, known as CJK STROKE ST, primarily serves a formatting purpose in digital text. It is predominantly used in Chinese, Japanese, and Korean (CJK) writing systems, although it is not specific to any single language or system within this group. The CJK STROKE ST character helps to visually separate sections of text, particularly when using the traditional writing style, where a stroke is an essential component of each character. It assists in maintaining readability and clarity while formatting text in digital documents. In its role as a separator or divider, it contributes to a well-structured, easy-to-read layout in CJK texts. Despite its limited usage in other writing systems outside the CJK group, the character remains an important part of digital typography within these languages, ensuring precise formatting and legibility for readers.

How to type the symbol on Windows

Hold Alt and type 12761 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+31D9. 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+31D9 to binary: 00110001 11011001. 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 10000111 10011001
