Description

The Unicode character U+246C, known as CIRCLED NUMBER THIRTEEN, is a digit-like glyph often used in mathematical and statistical expressions where the use of regular numerals might be ambiguous or inappropriate. It forms part of the Unicode range for Mathematical Alphanumeric Symbols (1D400-1D7FF), which includes various symbols for representing numbers and operations within a circular format. Its typical usage in digital text is to denote the number thirteen in a visually distinct, round format, often used in equations, diagrams, or other mathematical contexts where clarity of presentation is crucial. While this character may not have any significant cultural, linguistic, or technical context on its own, it contributes to precise and unambiguous communication in specialized fields such as mathematics, computer science, and engineering.

How to type the symbol on Windows

Hold Alt and type 9324 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+246C. 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+246C to binary: 00100100 01101100. 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:
