Description

The Unicode character U+1AC9, also known as the COMBINING DOUBLE PLUS SIGN ABOVE, primarily serves a role in digital text as an accent or diacritic mark. In typography, it is used to place a doubled plus sign (+) above another character or letter, often used in mathematical expressions or equations. This character can be combined with other letters or symbols to indicate specific meanings or relationships within the context of its usage. It does not have any notable cultural, linguistic, or technical context outside of its role as an accent or diacritic mark in digital text. Accuracy is paramount when using this character, as its incorrect application can lead to misinterpretation or errors in the intended mathematical expression or equation.

How to type the symbol on Windows

Hold Alt and type 6857 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+1AC9. 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+1AC9 to binary: 00011010 11001001. 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:
    11100001 10101011 10001001
