Description

The Unicode character U+224B, also known as the Triple Tilde (˜˜˜), is a relatively obscure symbol primarily used in digital text for specific mathematical or typographic purposes. Its primary role lies in representing an undefined variable or unknown element in various mathematical contexts. In linguistic applications, it is sometimes employed to indicate an elongated vowel sound in certain languages that utilize diacritical marks for stress and pronunciation guidance. While its usage may be limited, the Triple Tilde remains an essential tool for those working within specific fields of mathematics, typography, or linguistics where precise representation of unknowns or extended vowels is crucial.

How to type the symbol on Windows

Hold Alt and type 8779 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+224B. 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+224B to binary: 00100010 01001011. 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 10001001 10001011
