Description

The Unicode character U+29CB, known as TRIANGLE WITH UNDERBAR, is a mathematical symbol that represents a triangle with an underbar in its middle part. In digital text, it is often used to illustrate the concept of a "triangle inequality" or other mathematical properties related to triangles in geometry and trigonometry. The character is not culturally specific and has no linguistic significance. Its primary purpose is technical, serving as an efficient way to convey complex geometric relationships within digital text, such as in mathematical formulas or computer programming contexts. Its use helps to clearly represent the relationship between elements in a visual manner that is easily understood by readers familiar with these concepts.

How to type the symbol on Windows

Hold Alt and type 10699 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+29CB. 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+29CB to binary: 00101001 11001011. 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 10001011
