Description

The Unicode character U+2116 is known as the NUMERO SIGN. It is a typographical symbol primarily used in mathematical expressions and computer programming for representing a number or numeric value. This character serves an important role in digital text, especially in contexts where precision and clarity are essential, such as in scientific documents, engineering specifications, and software development. Although not widely recognized or commonly used outside of these specialized fields, the NUMERO SIGN has found its niche due to its ability to clearly distinguish between a numeric value and other types of textual content. In programming languages like C and Python, it is often used in conjunction with other symbols and operators to enhance the readability and efficiency of code. Overall, U+2116 plays a crucial role in digital communication where precise numeric representation is necessary.

How to type the symbol on Windows

Hold Alt and type 8470 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+2116. 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+2116 to binary: 00100001 00010110. 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 10000100 10010110
