Description

The Unicode character U+29DD, known as the TIE OVER INFINITY, is a typographical symbol that plays a significant role in digital text. It is used to represent the mathematical concept of infinity with a vertical line extending over it, symbolizing an infinite series or sequence. While not widely utilized in everyday language, this character is often found in specialized fields such as mathematics and computer science, where precise communication of complex ideas is crucial. Its unique design distinguishes it from other symbols for infinity, like the lemniscate (U+2113) or the simple infinity sign (U+267E).

How to type the symbol on Windows

Hold Alt and type 10717 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+29DD. 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+29DD to binary: 00101001 11011101. 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 10100111 10011101
