Description

The Unicode character U+2AEA, known as the Double Down Tack (⏚), holds a unique role in digital typography. It is primarily used to signify a change of direction in text that is written or printed vertically, such as in vertical Japanese script. This symbol aids in maintaining consistency and clarity when rendering text in vertical orientations. While the Double Down Tack may not be commonly employed in everyday digital communication, it remains an essential tool for ensuring precise typographical representation in specialized applications and languages. The character is rooted in Unicode version 3.0, released in October 1998, highlighting its long-standing significance within the realm of text encoding.

How to type the symbol on Windows

Hold Alt and type 10986 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+2AEA. 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+2AEA to binary: 00101010 11101010. 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:
    11100010 10101011 10101010
