Description

The Unicode character U+2A25, also known as the Plus Sign with Dot Below, is a typographical symbol that serves a specific role in digital text. It is commonly used to denote an operator or sign that adds a positive value to another number or element in mathematical equations and expressions. This particular symbol stands out from other plus signs due to its unique aesthetic feature: a small dot located below the main body of the character, giving it a distinct visual appearance. Although this character may seem like a minor variation of the standard plus sign, its inclusion in the Unicode Standard (version 6.0 and later) emphasizes the importance of diversity in digital typography. The Plus Sign with Dot Below can be utilized in various contexts, including mathematical texts, coding languages, and even art or design work where a unique visual element is desired. Despite its relatively recent addition to the Unicode Standard, the Plus Sign with Dot Below has already gained traction among users who appreciate its distinctiveness and utility within digital text.

How to type the symbol on Windows

Hold Alt and type 10789 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+2A25. 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+2A25 to binary: 00101010 00100101. 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 10101000 10100101
